RT7237J Datasheet Synchronous Step-Down Converter

Manufacturer: Richtek

Overview: Design Tools ® RT7237J 2A, 18V, 340kHz Synchronous Step-Down Converter.

General Description

The RT7237J is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.5V to 18V input supply.

The RT7237J's current mode architecture and external compensation allow the transient response to be optimized over a wide input range and loads.

Cycle-bycycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up.
