PMA 4000 Series DC/DC regulators Input 3.0 - 3.6V Output Current 12A Key Features * Surface mountable * Low profile, max 8.5mm (0.33 in) * High efficiency * Low weight * Designed for Environment, DfE * Lead-free / Bromine-free * Robust design The PMA series of DC/DC regulators (POL) are intended to be used as local distributed power sources in distributed power architecture level 4. The PMA series use a ceramic substrate with fine-pitch components technology and a high degree of silicon integration. Together with the electrical design using low Rds-On MOSFET, this provides excellent thermal management, high reliability and high efficiency. The high efficiency makes it possible to operate over a wide temperature range, without adding any external heat dissipator. At forced convection cooling >1 m/s (200 lfm), the PMA typically delivers full power up to +80 C ambient temperature. The high reliability and the low profile of the PMA E series makes them particularly suited for the communications equipment of today and tomorrow and applications with board spacing down to 15 mm (0.6 in). The flat case top enables pick-and-place handling and provides a surface for attachment to cooling surfaces in areas with limited air flow. These products are manufactured using the most advanced technologies and materials to comply with environmental requirements. Designed to meet high reliability requirements of systems manufacturers, the PMA responds to world-class specifications. Ericsson Power Modules is an ISO 9001/14001 certified supplier.

The DC/DC regulator should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. The input source must be isolated by minimum Reinforced or Double insulation from the primary circuit in accordance with IEC/EN/UL 60 950. If the input voltage to the DC/ DC regulator is SELV (Safety Extra Low Voltage) then the output remains SELV under normal and abnormal operating conditions. It is recommended that a slow blow fuse with a rating of 25A be used at the input of each DC/DC regulator. If a fault occurs in the regulator that imposes a short circuit on the input source, this fuse will provide the following functions: * Isolate the faulty DC/DC regulator from the input power source not to affect the operation of other parts of the system.

The RC function is CMOS open drain compatible. Maximum sink current is 1mA. The (RC) and (Select) pins have identical functions meaning that the functions may be inverted. If either one of the pins is shorted to ground the regulator is turned off. If both pins are are shorted to ground or both pins are disconnected the regulator is turned on. The radiated EMI performance of the DC/DC regulator will be optimised by including a ground plane in the PCB area under the DC/DC regulator. This approach will return switching noise to ground as directly as possible, with improvements to both emission and susceptibility. Positive logic: To choose positive logic, leave the Select pin open = 1. Negative logic: To choose negative logic, connect the Select pin to GND = 0. With the RC pin, i.e. with a suitable open collector function, the ON/OFF condition of the regulator may be controlled. RC Select Regulator condition 0 0 ON 1 0 OFF 0 1 OFF 1 1 ON 0= Defined as low voltage level, 0-0.3V 1= Defined as high voltage level, approx. 4V, (internal level) Remote Sense All PMA 4000 Series DC/DC regulators have a positive remote sense pin that can be used to compensate for moderate amounts of resistance in the distribution system and allow for voltage regulation at the load or other selected point. The remote sense line will carry very little current and does not need a large cross sectional area. However, the sense line on the PCB should be located close to a ground trace or ground plane. The remote sense circuitry will compensate for up to 10% voltage drop between the sense voltage and the voltage at the output pins from VOnom. If the remote sense is not needed the sense pin should be connected to +Out. 16 PMA 4000 Series Datasheet EN/LZT 146 012 R3A (c) Ericsson Power Modules, November 2003 Operating Information Output Voltage Adjust (Vadj) Input And Output Impedance The impedance of both the power source and the load will interact with the impedance of the DC/DC regulator. It is most important to have a low characteristic impedance, both at the input and output, as the regulators have a low energy storage capability. Use capacitors across the input if the source inductance is greater than 4.7H. Suitable input capacitors are 47F-220F low ESR ceramics. Max output capacitance is 5000F. The use of low ESR capacitors is important and should be <15 m. All PMA 4000 Series DC/DC regulators have an Output Voltage adjust pin (Vadj). This pin can be used to adjust the output voltage above or below Output voltage initial setting. Note that at increased output voltages the maximum power rating of the regulator remains the same, and the output current capability will decrease correspondingly. To decrease the output voltage the resistor should be connected between Vadj pin and the Sense pin. To increase the voltage the resistor should be connected between Vadj pin and the GND pin. The resistor value of the Output voltage adjust function is according to information given under the output section. +Out +Out Sense Radj Load Radj Vadj GND Decrease Load Vadj GND Increase Circuit configuration for output voltage adjust Current Limit Protection The PMA 4000 Series DC/DC regulators include current limiting circuitry that allows them to withstand continuous overloads or short circuit conditions on the output. The current limit is of hick-up mode type. The regulator will resume normal operation after removal of the overload. The load distribution system should be designed to carry the maximum output short circuit current specified. Over Temperature Protection (OTP) The PMA 4000 Series DC/DC regulators are protected from thermal overload by an internal over temperature shutdown circuit. When the case temperature (center of case ) exceeds 140 C the regulator will shut down immediately. The regulator will return to normal operation when the over temperature degrades. PMA 4000 Series Datasheet Maximum Capacitive Load When powering loads with significant dynamic current requirements, the voltage regulation at the load can be improved by addition of decoupling capacitance at the load. The most effective technique is to locate low ESR ceramic capacitors as close to the load as possible, using several capacitors to lower the total ESR. These ceramic capacitors will handle short duration high-frequency components of dynamic load changes. In addition, higher values of capacitors should be used to handle the mid-frequency components. It is equally important to use good design practise when configuring the DC distribution system. Low resistance and low inductance PCB layouts and cabling should be used. Remember that when using remote sensing, all resistance, inductance and capacitance of the distribution system is within the feedback loop of the regulator. This can affect on the regulators compensation and the resulting stability and dynamic response performance. The PMA 4000 series regulator can accept up to 5mF of capacitive load on the output at full load. This gives <500F/A of IO. Parallel Operation The PMA 4000 Series DC/DC regulators can be connected in parallel with a common input. Paralleling is accomplished by connecting the output voltage pins directly and using a load sharing device on the input. Layout considerations should be made to avoid load imbalance and it is recommended not to use more power than that of each individual regulator. For more details on paralleling, please consult the separate Application Note AN202A. EN/LZT 146 012 R3A (c) Ericsson Power Modules, November 2003 17 Thermal Considerations General The PMA 4000 Series DC/DC regulators are designed to operate in a variety of thermal environments, however sufficient cooling should be provided to help ensure reliable operation. Heat is removed by conduction, convection and radiation to the surrounding environment. Increased airflow enhances the heat transfer via convection. The available load current vs. ambient air temperature and airflow at Vin=3.3 V for each model is according to the information given under the output section. Proper cooling can be verified by measuring the temperature on top of the case. Calculation of ambient temperature By using the thermal resistance the maximum allowed ambient temperature can be calculated. A. The powerloss is calculated by using the formula ((1/) - 1) x output power = power losses. = efficiency of regulator. Example: 95% = 0.95 B. Find the value of the thermal resistance Rth C-A in the diagram by using the airflow speed at the module. Take the thermal resistance x powerloss to get the temperature increase.

Test conditions: The test is done in a wind tunnel with a cross section of 305x305 mm, the DC/DC regulator horisontally mounted on a 2 layer PCB with a size of 230x160 mm. C. Max allowed calculated ambient temperature is: Max TC of DC/DC regulator - temperature increase. Example: PMA 4118H at 1m/s: A. ((1/0.88) - 1) x 18W = 2.45W B. 2.45W x 11.7C/W = 28.7C C.110C - 28.7C = max ambient temperature is 81C The real temperature will be dependent on several factors, like PCB size and type, direction of airflow, air turbulence etc. It is recommended to verify the temperature by testing. 18 PMA 4000 Series Datasheet EN/LZT 146 012 R3A (c) Ericsson Power Modules, November 2003 Miscellaneous Soldering Information The PMA 4000 series DC/DC regulators are intended for reflow soldering processes. Extra precautions must be taken when reflow-soldering the module. Neglecting the soldering information provided may result in permanent damage or significant degradation of the regulator performance. No responsibility is assumed if these recommendations are not strictly followed. pin temperature case temperature [C] 300 max case temperature @ 215C (Sn-Pb solders) 250 reflow rampup max 3/s 200 150 The regulator may be reflow soldered using vapour phase reflow (VPR) or forced convection reflow processes. The high thermal mass of the component and its effect on the temperature differences (T) over a PCB means that particular attention should be paid to other temperature sensitive components. For successful soldering of the PMA 4000 series DC/DC regulators, both pin temperature and case temperature must be monitored: * Minimum temperature of the pins: to ensure reliable solder joints * Maximum temperature of the regulator case: to avoid overheating Minimum temperature: Most important is to ensure that the pins on the coolest side reach sufficient soldering temperature for a sufficient time. Therefore, the pin temperature measurements should be done on both sides of the module, preferrably on the middle pins (3/4 and 11/12). cooling max 5/s preheat max 3/s 100 soak zone (150C180C) 30-180s 50 reflow zone 0 0 70 140 210 280 Time 350 Conventional Sn-Pb convection solder process For conventional Sn-Pb solder processes, the PMA 4000 series regulator is qualified for MSL 1 according to Jedec standard (J-STD-020b July 2002). During reflow, the case temperature must not exceed 215C at any time. The pins of the module are palladium plated. In order to guarantee a reliable solder joint, a pin temperature (TP) in excess of the solder fusing temperatue (183C for Sn/Pb 63/37) for 25 seconds, and a peak temperature above 195C should be reached. Maximum temperature: To avoid damage to the module, the reflow profile should be optimised to avoid overheating. The case temperature (TC) should be monitored with a thermocouple attached to the center of the top of the case using an adhesive or heat conductive paste. A sufficiently extended soak time is recommended to ensure an even temperature throughout the PCB, for both small and large components. To reduce the risk of overheating the module it is also recommended to minimise the time in reflow as much as possible.
