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.
