General Absolute Maximum Ratings Characteristics min max Unit TC Maximum Operating Case Temperature -40 +100 C TS Storage temperature -40 +125 C VI Input voltage -0.5 +80 Vdc VISO Isolation voltage (input to output test voltage) 1,500 Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and performance may degrade in an unspecified manner. For design margin and to enhance system reliability, it is recommended that the PKM 4000 series DC/DC power modules are operated at case temperatures below 90C.

If connected to a 60V DC power system, reinforced insulation must be provided in the power supply that isolates the input from the mains. Single fault testing in the power supply must be performed in combination with the DC/DC power module to demonstrate that the output meets the requirement for SELV. One pole of the input and one pole of the output is to be grounded or both are to be kept floating. Data Sheet AE/LZT 108 4913 R2 (c) Ericsson Inc., Microelectronics, May 2001 Safety (continued) The galvanic isolation is verified in an electric strength test. The test voltage (VISO) between input and output is 1,500 Vdc or 60 sec. Leakage current is less than 1A @ 50Vdc. Flammability ratings of the terminal support and internal plastic construction details meet UL 94V-0. A fuse should be used at the input of each PKM 4000 series power module. If a fault occurs in the power module, that imposes a short on the input source, this fuse will provide the following two functions: * Isolate the failed module from the input source so that the remainder of the system may continue operation. * Protect the distribution wiring from overheating. A fast blow fuse should be used with a rating of 10A or less. It is recommended to use a fuse with the lowest current rating, that is suitable for the application.

At input voltages exceeding 75V, the power loss will be higher than at normal input voltage and TC must be limited to absolute max +100 C. The absolute max continuous input voltage is 80V DC. All PKM 4000 DC/DC power modules have latching output overvoltage protection. In the event of an overvoltage condition, the power module will shut down. The power module can be restarted by cycling the input voltage. Turn-(on/off) Input Voltage (VIon/VIoff) The power module monitors the input voltage and will turn on and turn off at predetermined levels. See Input Table on page 2. Output Voltage Adjust (Trim) Remote Control (RC) Voltage Trimming The PKM 4000 series DC/DC power modules have two remote on/off options available. Negative logic remote on/off is the standard option orderable without a suffix added to the part number. Negative logic remote on/off turns the module off during a logic high voltage on the on/off pin, and on during a logic low state. Positive logic remote on/off is orderable by adding the suffix "P" to the end of the part number. Positive logic remote on/off turns the module on during a logic high and off during a logic low state. The RC pin can be wired directly to -In, to allow the module to power up automatically without the need for control signals. All PKM 4000 series DC/DC power modules have an Output Voltage Adjust pin. This pin can be used to adjust the output voltage above or below VOi. When increasing the output voltage, the voltage at the output pins (including any remote sensing offset) must be kept below the overvoltage trip point. Also note that at elevated output voltages the maximum power rating of the module remains the same, and the output current capability will decrease correspondingly. These modules trim exactly like the other major competitors quarter-brick modules. To decrease VO connect Radj from - SEN to Trim To increase VO connect Radj from + SEN to Trim A mechanical switch or an open collector transistor or FET can be used to drive the RC inputs. The device must be capable of sinking up to 1mA at a low level voltage of 1.0V, maximum of 15V dc, for the primary RC. Standard Remote Control RC (primary) Power module Low Open/High ON OFF Optional Remote Control (P) RC (primary) Power module Low Open/High OFF ON Remote Sense All PKM 4000 series DC/DC power modules have remote sense 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 lines will carry very little current and do not need a large cross sectional area. However, the sense lines on a PCB should be located close to a ground trace or ground plane. In a discrete wiring situation, the usage of twisted pair wires or other technique for reducing noise susceptibility is recommended. The power module will compensate for up to 0.5V voltage drop between the sense voltage and the voltage at the power module output pins. The output voltage and the remote sense voltage offset must be less than the minimum overvoltage trip point. Current Limiting General Characteristics All PKM 4000 series DC/DC power modules include current limiting circuitry that makes them able to withstand continuous overloads or short circuit conditions on the output. The output voltage will decrease toward zero for heavy overloads. The power module will resume normal operation after removal of the overload. The load distribution system should be designed to carry the maximum short circuit output current specified.

The diodes on the power module outputs allow a failed module to remove itself from the shared group without pulling down the common output bus. This configuration can be extended to additional numbers of power modules and they can also be controlled individually or in groups by means of signals to the primary RC inputs. PKM1 PKM2 Low resistance and low inductance PCB (printed circuit board) layouts and cabling should be used. Remember that when using remote sensing, all the resistance, inductance and capacitance of the distribution system is within the feedback loop of the power module. This can have an effect on the modules compensation and the resulting stability and dynamic response performance. As a rule of thumb, 100 F/A of output current can be used without any additional analysis. For example, with a 20A (max PO 100W) power module, values of decoupling capacitance up to 2000 F can be used without regard to stability. With larger values of capacitance, the load transient recovery time can exceed the specified value. As much of the capacitance as possible should be outside of the remote sensing loop and close to the load.The absolute maximum value of output capacitance is 10,000 F. For values larger than this contact your local Ericsson representative. Quality PKM Reliability Output ripple is measured as the peak to peak voltage from 0 to 20MHz which includes the noise voltage and fundamental ripple. The calculated MTBF of the PKM 4000 module family is greater than (>) 2.8 million hours using Bellcore TR-332 methodology. The calculation is valid for a 90C baseplate temperature. Demonstrated MTBF has been in the range of 3.0 to 3.2 million hours. Over Temperature Protection Quality Statement Output Ripple & Noise (VOac) The PKM 4000 DC/DC power modules are protected from thermal overload by an internal over temperature shutdown circuit. When the case temperature exceeds +110C (+10, -5C), the power module will automatically shut down (latching). To restart the module the input voltage must be cycled. Input and Output Impedance The impedance of both the power source and the load will interact with the impedence of the DC/DC power module. It is most important to have the ratio between L and C as low as possible, i.e. a low characteristic impedance, both at the input and output, as the power modules have a low energy storage capability. The PKM 4000 series of DC/DC power modules has been designed to be completely stable without the need for external capacitors on the input or output when configured with low inductance input and output circuits. The performance in some applications can be enhanced by the addition of external capacitance as described below. If the distribution of the input voltage source to the power module contains significant inductance, the addition of a 220-470 F capacitor across the input of the power module will help insure stability. This capacitor is not required when powering the module from a low impedance source with short, low inductance, input power leads. Output Capacitance When powering loads with significant dynamic current requirements, the voltage regulation at the load can be improved by the 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 effective ESR. These ceramic capacitors will handle the short duration high frequency components of the dynamic current requirement. In addition, higher values of electrolytic capacitors should be used to handle the mid-frequency components. It is equally important to use good design practices when configuring the DC distribution system.
