RT6234A/B

3A, 18V, 500kHz, ACOT^TMStep-Down Converter

General Description

Features

^Integrated 130mΩ / 70mΩ MOSFETs

^4.5V to 18V Supply Voltage Range

^500kHz Switching Frequency

^ACOT Control

The RT6234A/B is a high-efficiency, monolithic

synchronous step-downDC-DC converter that can deliver

up to 3A output current from a 4.5V to 18V input supply.

The RT6234A/B adopts ACOT architecture to allow the

transient response to be improved and keep in constant

frequency. Cycle-by-cycle current limit provides protection

against shorted outputs and soft-start eliminates input

current surge during start-up. Fault conditions also include

output under voltage protection and thermal shutdown.

^0.8V 2% Voltage Reference

^Output Adjustable from 0.8V to 6.5V

^Monotonic Start-Up into Pre-Biased Outputs

Applications

 Set Top Box

 Portable TV

 Access Point Router

 DSL Modem

 LCD TV
