LTC7891 Datasheet (Analog Devices) - Synchronous Step-Down Controller

LTC7891, Synchronous Step-Down Controller

The LTC7891 is a high performance, step-down, dc-to-dc switching regulator controller that drives all N-channel synchronous gallium nitride (GaN) field effect transistor (FET) power stages from input voltages up to 100 V.

The LTC7891 solves many of the challenges traditionally faced when using GaN F
