The EVB can be used to easily manipulate the MC33730 functions and validate the capabilities of the IC. The board provides connections that allow the user to supply MPCxx MCUs via hard wired connections. 3.1 EVB Features * * * * * * * * * * 3.2 Provides all regulated voltages for MPC5XX MCUs and other MCUs logic and analog functions Adjustable frequency switching buck regulator with slew-rate control provided by jumpers Power sequencing provided Programmable voltages VDDL, VDD3 - 3% accuracy (P1, P2, and P3 jumpers) Programmable standby regulator VKAM - (P1, P2, and P3 jumpers) operating down to 4.5V at KA_VBAT pin VDD3 can be programmed as an optional second standby regulator (P1, P2, and P3 jumpers) Provides two 5.0V protected supplies for sensors Provides reverse battery protection FET gate drive (either a diode or PFD gate drive) Provides necessary MCU monitoring and fail-safe support Pb-free packaging designated by suffix code EK Required Equipment Minimum required equipment: Power supply: 4.5 to 26.5V KIT33730EKEVBE Evaluation Board, Rev. 1.0 4 Freescale Semiconductor Using Hardware 4 Using Hardware This EVB consists of a MC33730 switching power supply, power conditioning circuitry, and a set of Input Select Jumpers. MC33730 Circuit. 4.1 LED Display Seven LED's are provided as visual output devices for the MC33730 EVB board. A list of the LED devices is shown below: 1. VDDH LED - Indicates when VDDH supply is operating. 2. VDDL LED - Indicates that the VDDL supply is operating. 3. VDD3 LED - Indicates that the VDD3 supply is operating. 4. VREF1 LED - Indicates that the VREF1 reference is operating. 5. VREF2 LED - Indicates that the VREF2 reference is operating. 6. IGN LED - Indicates Battery supplied to Vign. 7. IGNSW LED - Indicates that the VDD3 supply is operating. 4.2 Selection Jumper Definitions The EVB contains four jumpers that provide certain selections for the MC33730 as follows (Bold = default factory setting): 4.2.1 P1, P2, P3 Jumpers The P1, P2, and P3 jumpers are used to determine what voltage levels will be supplied by the VDD3, VDDL and VKAM supplies. The pins are used to hardwire the settings with the MC33730 reading the values at startup. The table below shows the various conditions that can be set. P1 P2 P3 VDD3 VDDL VKAM High High High 3.3V 2.6V 2.6V High High Low 3.3V 3.3V 3.3V High Low High 3.3V 1.5V 1.0V High Low Low 3.3V 3.3V 1.0V Low High High 3.3V Standby 3.3V 1.0V Low High Low 2.0 3.15V 5.0V Low Low High 2.6V Standby 3.3V 1.0V Low Low Low 2.6V Standby 3.3V 1.5V KIT33730EKEVBE Evaluation Board, Rev. 1.0 Freescale Semiconductor 5 Using Hardware 4.2.2 VDD3 Jumper In the state where VDD3 is desired to be in standby, the VDD3 jumper is used to short the Base of the VDD3 transistor to ground. The default case (Normal) is to leave the base connected to VDD3_B. Jumper should be connected to Normal except for the cases where P1, P2, and P3 are as follows: P1 4.2.3 P2 P3 Low High High 3.3V Standby VDD3 Low Low High 2.6V Standby Low Low Low 2.6V Standby Slew Rate (SR) Jumper The Slew Rate Control Jumper Allows For Configurable Slew Rates For The Switching Regulator. Connected To Boot The Slow Slew Rate Is Active And Connected To Sw The Fast Slew Rate Is Selected. The Pin Can Be Left Open Which Results In The Medium Slew Rate Control. SR CONDITION FOR SLEW RATE Boot Slow Slew rate Open Medium Slew rate SW Fast Slew rate Setup Pins The 33730 has multiple pins used to do initial setup for the IC. When the IC is powered up a series of checks are done to determine the P1, P2, P3, HRT, SR and FREQ state. The P1, P2, and P3 states are connected to jumpers to allow the user to configure the supply rails easily. Once the IC has determined their state at startup, the status is latched into registers and changing the jumpers does not affect the operation until the next POR or start up occurs. The HRT pin is set to 10k. The resistor connected to HRT is R1. The SR state is determined by the SR jumper. The slew rate of the switching regulator can be selected to range from slow, medium and fast depending on the location (or open) of the jumper. The FREQ pin is connected to ground via a 10kohm resistor. This pin resistance to ground determines the frequency operation of the switching regulator. The resistor connected to FREQ is R9. Output Supply Pins There are multiple output power supplies integrated into the integrated circuit. The main switching regulator, VDDH, uses a fixed frequency PWM voltage mode control. It has a 3.5A current limit (typical) and the slew-rate is adjustable via a control pin to reduce switching noise. The switching regulator has an adjustable frequency oscillator, which allows the user to optimize its operation over a wide range of input voltages and component values. The VDDH regulator supplies a 5v rail and is used as the internal power supply for VREF1 and VREF2 along with the external rail for VDD3 and VDDL. Associated with the VDDH regulator is the INV and VCOMP pins which have been connected to optimize the compensation for the step down regulator. A bootstrap capacitor is connected from the VSW pin to the BOOT pin. The linear regulators can be configured either as two normal mode regulators (VDD3, VDDL) and one standby regulator (VKAM), or as one normal mode linear regulator (VDDL) and two standby regulators (VKAM and VDD3 Standby). Two protected outputs, VREF1 and VREF2, are used to provide power to external sensors. KIT33730EKEVBE Evaluation Board, Rev. 1.0 6 Freescale Semiconductor Using Hardware All of the output supplies have been brought out to two sets of connectors. The SV1 is available to monitor the output voltages while SV3 is designed to connect to the loads or a micro motherboard. The SV1 connector is pinned out as follows: PIN NODE 1 AGND 2 VREF2 3 VREF1 4 VKAM 5 N/C 6 VDDH 7 VDDL 8 VDD3 The SV3 connector is pinned out as follows: PIN NODE 1 Battery 2 Battery 3 VDDH 4 VDDH 5 VDD3 6 VDD3 7 VDDL 8 VDDL 9 N/C 10 AGND 11 VKAM 12 RST3 13 VDDA 14 RSTKAM 15 VREF1 16 RSTL 17 VREF2 18 RSTH 19 N/C 20 REGON 21 IGN_ON 22 IGN 23 KA 24 AGND 25 AGND 26 AGND The SV3 connector also contains a number of other pin functions including the reset pins, the REGON pin and the IGN_ON and IGN pins. KIT33730EKEVBE Evaluation Board, Rev. 1.0 Freescale Semiconductor 7 Using Hardware 4.2.4 MC33730 EVB Setup To use the evaluation board the Battery connection must be made to the +12v and GND connector. Turn on the power supply and ensure the voltage is in the normal operating range. To apply IGN, move the slider switch to the On position (slider toward Battery connection). Ensure the IGN_ON and IGNSW LED's are lit. The LED's for the voltage rails will also turn on and the user can monitor the voltages and apply loads via the connectors.
