RT8292B

2A, 23V, 1.2MHz Synchronous Step-Down Converter

General Description

Features

1.5% High Accuracy Feedback Voltage

The RT8292B is a high efficiency, monolithic synchronous

step-down DC/DC converter that can deliver up to 2A

output current from a 4.5V to 23V input supply. The

RT8292B'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 RT8292B also provides under

voltage protection and thermal shutdown protection. The

low current (<3μA) shutdown mode provides output

disconnction, enabling easy power management in

battery-powered systems. The RT8292B is available in a

SOP-8 (Exposed Pad) package.
