Introduction

General Product Information

General Description

The RT7247C 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 RT7247C's current mode architecture and external

compensation allow the transient response to be optimized over a wide range of loads and output capacitors.

Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge

during start-up. The RT7247C also provides output under voltage protection and thermal shutdown protection. The

low current (<3μA) shutdown mode provides output disconnection, enabling easy power management in

battery-powered systems. The RT7247C is available in an SOP-8 (Exposed Pad) package.
