RT6212A/B

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

General Description

Features

 Integrated 163m/86m MOSFETs

 4.5V to 18V Supply Voltage Range

 500kHz Switching Frequency

The RT6212A/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 RT6212A/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.

 ACOT Control

 Feedback Reference Voltage 0.8V ± 1.5%

 Feedback Reference Voltage 0.765V ± 1.5%

 Internal Start-Up into Pre-Biased Outputs

 Compact Package : TSOT-23-6 Pin

 Input Under-Voltage Lockout

 Over-Current Protection and Hiccup

Applications

 Set-Top Boxes

 Portable TVs
