ISL99135B
ISL99135B is 25A/35A DrMOS Module manufactured by Renesas.
- Part of the ISL99125B comparator family.
- Part of the ISL99125B comparator family.
feature a three-state PWM input that, working together with Intersil’s 5V PWM controllers (such as ISL6398, ISL9585x, ISL637x, ISL633x, ISL636x, and ISL68201), will provide a robust solution in the event of abnormal operating conditions.
The ISL99125B, ISL99135B support high-efficiency operations not only at heavy loads, but also at light loads via its diode emulation capability. Diode emulation can be disabled for those applications where variable frequency operation is not desired at light loads.
ISL99125B, ISL99135B also feature very low shutdown supply current (3µA) to ensure the low power consumption, especially designed for IMVP8 PS4 shutdown operation.
