The MP1924 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 less than 5ns in time delay. Under-voltage lockout on both the high side and low side supplies force their outputs low in case of an insufficient supply. The integrated bootstrap diode reduces the external component count.

EV1924-S-00A Evaluation Kit 100V, 4A Half-Bridge Gate Driver Evaluation Board
The EV1924-S-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.
