EV1924-R-00A
100V, 4A Half-Bridge Gate Driver
Evaluation Board
DESCRIPTION
The EV1924-R-00A is an evaluation board for
the MP1924, a high frequency Half-Bridge gate
driver. Its high-side and low-side driver
channels are independently controlled and
matched with a time delay of less than 5ns.
The demo board is configured as a buck
converter. INH and INL are independent signals
of each other. Complementary PWMs with
proper dead time should be implemented for
INH and INL.

QUICK START GUIDE
1. Preset driver power supply voltage range of 9V-16V.
2. Preset input power supply voltage range of 0V-100V.
3. Attach a couple of complementary PWMs with proper dead time to the CN4.
4. Attach driver power supply to the VDD and GND terminals respectively.
5. Attach input power supply to the VIN and GND terminals respectively.
6. Attach load to the LOAD and GND terminals respectively.
7. Turn on driver power supply.
Check INH, INL, DRVH and DRVL signals, make sure a sufficient dead time of DRVH and DRVL
has been established before following steps:
8. Turn on input power supply.
9. Turn on the load, check output voltage and current.
10. To turn off the system, please follow these steps:
a. Turn off load.
b. Turn off VIN.
c. Turn off VDD.
