LTC7890/1 Synchronous Step-Down Controllers

Analog Devices LTC7890/1 Synchronous Step-Down Controllers are high-performance, 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 100V. The LTC7890/1 Controllers are the solution to challenges traditionally faced when using GaN FETs. The devices simplify the application design with no protection diodes or additional external components needed compared to a silicon metal-oxide-semiconductor field-effect transistor (MOSFET) solution.
