The Evaluation Board is designed to provide the user with the ability to configure the part using a single 9V to 18V input supply, a dual supply, or with each regulator supplied individually. The Evaluation Board has three buck regulators that are setup for outputs of 3.3V at 1.5A, 2.5V at 1.25A and 1.25V at 1.25A and an LDO with a 0.9V at 400mA output. Inputs to enable each output channel are provided as well as a Power Good LED indicator.

As a result, the output current available from CH1 is not the full 1.5A, but the current remaining after supplying VIN2 and VIN3. Similarly the current available for CH3 is not the full 1.25A.

EVB Setup Configuration Diagram KIT34700EPEVBE Evaluation Board, Rev. 1.0 Freescale Semiconductor 6 Using the Hardware 6 Using the Hardware Use the following steps to verify that the Evaluation Board is operational: a) Verify jumpers are installed as shown in Jumper Connections Section. Use the default settings. b) Check polarity and connect a 12V, 2A supply to VIN1 terminal. c) Check 12V supply current with all the regulators disabled. The supply current should not exceed 15mA. d) Enable CH1 by moving EN1 jumper to 1-2 position. Verify 3.3V channel is operating by measuring voltage at VOUT1 terminal. VOUT1 is typically 3.38V. e) Enable CH2 by moving the EN2 jumper to the 1-2 position. Verify the 2.5V channel is operating by measuring the voltage at the VOUT2 terminal. VOUT2 is typically 2.49V. f) Enable CH3 by moving EN3 jumper to 1-2 position. Verify that the 1.25V channel is operating by measuring the voltage at the VOUT3 terminal. VOUT3 is typically 1.28V. g) Enable LDO by moving EN_LDO jumper to 1-2 position. Verify 0.9V channel is operating by measuring voltage at VOUT_LDO terminal. VOUT_LDO is typically 0.9V. h) If all the regulators are up and running, verify that the PGOOD LED (D2) is on. After board verification, it can be reconfigured and tested per system requirements. 6.1 Jumper Connections A description of the jumper settings is given in the following table.

The FET, Q1, is required for signal inversion and to drive the LED current. The resistor, R26, limits the LED current. The jumper (PGOOD_LED) disconnects the status LED for making efficiency and quiescent current measurements. The status LED is connected to the output of CH1 when the jumper is installed. The test point PGOOD is the open drain output of the PGOOD pin. It is pulled up to VGREG by resistor R25. 6.3 Switch Nodes The evaluation board includes test points for monitoring the switch nodes of DC/DC 1, 2 and 3. The test points are located close to the output inductors of each channel. The switch nodes can be used to measure switching frequency, duty cycle, phase, and switch times. 6.4 Power Input Voltage The power input voltage for DC/DC1 (VIN1) is connected to the VIN1 terminal block. The VIN1 input is bypassed with bulk capacitors C27 and C28, and is connected to the IC input pin (VIN) by an RC filter, R2 and C20. Power inputs for DC/DC 2, and DC/DC 3 (VIN2, and VIN3) can be connected to the AUX_IN terminal or the output of DC/DC 1. By setting the jumpers (VIN2, and VIN3) to position 2-3, each regulator can be powered from the AUX_IN. By setting the jumpers to position 1-2, each regulator can be powered from the output of DC/DC 1. The power input voltage for the LDO (LDO_VIN) can be connected to the AUX_IN terminal or the output of DC/DC 3. By setting the jumper (LDO_VIN) to position 2-3, the LDO can be powered from the AUX_IN. By setting the jumper to position 1-2, the LDO can be powered from the output of DC/DC 3. The AUX_IN input is bypassed with bulk capacitors C30 and C31. For single supply operation, set VIN2, VIN3 and LDO_VIN to position 1-2. This connects the input of DC/DC 2 and DC/DC 3 to the output of DC/DC 1 and the LDO input to the output of DC/DC 3. For dual supply operation, set VIN2, and VIN3 to position 2-3. This connects the input of DC/DC 2 and DC/DC 3 to the AUX_IN terminal block. Set the LDO_VIN to either position depending on the application to connect the LDO input to the output of DC/DC 3 or the AUX_IN terminal. If each regulator needs to powered from a separate supply, two of the input power jumpers can be removed and an external supply connected directly to header position 2. Select KIT34700EPEVBE Evaluation Board, Rev. 1.0 Freescale Semiconductor 8 Using the Hardware the regulators with the lowest output power to connect directly to the header pin. The other two regulators are powered from VIN1 and AUX_IN. 6.5 Enables and Cascaded Sequencing The enable headers are currently configured for a simple enable/disable function. Setting the jumper to position 1-2 connects the enable pin to the VGREG output, enabling the respective regulator. Removing or setting the jumper to position 2-3 connects the enable pin to ground, disabling the respective regulator. However, the board has provisions to add a resistor divider to each enable pin which allows cascaded sequencing. Resistors R11, R12, R15, and R17 are installed and are 10K Ohm. By installing resistors R13, R14, R16, and R18 a voltage divider is formed at each enable pin. By setting the resistor divider of each enable, the voltage of the enable pin has to reach its’ threshold level before the regulator in the sequence is enabled. Note that the jumpers need to be removed and the output of the regulator in the previous sequence position be connected to pin 2 of the enable header. See the data sheet for more details on calculating the divider. 6.6 Leakage Current DC/DC 2 and DC/DC 3 each have ~400uA of leakage current that can cause the output to float up if there is not enough load current in the application. 1K Ohm resistors are installed at R36 and R37 (located on the bottom side of the PC board) to prevent VOUT2 and VOUT3 from floating when these channels are disabled. The 1K load can be removed if there is a minimum load of at least 4mA present on VOUT2 and VOUT3.
