DESCRIPTION
This is EV board documentation for MP18021A. The MP18021A is a high frequency, 100V half bridge N-channel power MOSFET driver. Its low side and high side driver channels are independently controlled and matched with a time delay of less than 5ns. Under-voltage lockout on both high side and low side supplies force their outputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count. This demo board is configured to a buck converter. INH and INL are independent signals of each other. For simplicity, the user only need to supply a PWM signal to this demo board and the on-board circuitry will generate INH and INL signals with proper dead time. In a real system, the controller will have to take care of dead time adjustment.

Unauthorized Photocopy and Duplication Prohibited. © 2013 MPS. All Rights Reserved. QUICK START GUIDE EV18021A-N-00A is configured in a buck converter. Below is the recommended setting for users to evaluate the EV board. User must watch for inductor saturation (do not set switching frequency too low) and over temperature (do not increase duty). 1. Preset Driver Power Supply between 9V-18V. 2. Preset Input Power Supply between 0V-100V. 3. Connect Driver Power Supply terminals to: a. Positive (+): VDD b. Negative (–): GND 4. Connect Input Power Supply terminals to: a. Positive (+): VPOWER b. Negative (–): GND 5. Connect Load to: a. Positive (+): LOAD b. Negative (–): LOADGND 6. Function Generator setting: a. Frequency: 200 KHz b. Logic High: 5V c. Logic Low: 0V d. Duty: 10% e. Rising/Falling Edge Slew Rate: As fast as possible 7. Connect Function Generator’s output to PWM and GND pins. Turn on Function Generator’s output. 8. Turn on Driver Power Supply. 9. Check INH, INL, DRVH and DRVL signals. Make sure there are dead time between DRVH high and DRVL high to avoid shoot through. 10. If all signals are correct, then turn on Input Power Supply. 11. User may load up to 4A of output current. Higher load current may cause overheat to the MOSFET. 12. To turn off the board, please follow these steps: a. Turn off load. b. Turn off Input Power Supply. c. Turn off Driver Power Supply.
