RT6232A/B

2A, 18V, 500kHz, ACOT^TMStep-Down Converter

General Description

Features

 Integrated 210m/120m MOSFETs

 4.5V to 18V Supply Voltage Range

 500kHz Switching Frequency

 ACOT Control

The RT6232A/B 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 RT6232A/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,

output over current protection, and thermal shutdown.

 0.8V 1.5% Voltage Reference

 Adjustable Soft-Start

 Power Good Indicator

 Monotonic Start-Up into Pre-biased Outputs

 Input Under-Voltage Lockout

 Over-Current Protection and Hiccup

Applications

 Set-Top Boxes

 Portable TVs
