RT6233A/B

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

General Description

Features

 Integrated 195m/105m MOSFETs

 4.5V to 18V Supply Voltage Range

 500kHz Switching Frequency

 ACOT Control

The RT6233A/B is a high-efficiency, monolithic

synchronous step-down DC-DC converter that can

deliver up to 3A peak output current from a 4.5V to 18V

input supply. The RT6233A/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
