RT6212B Datasheet Step-down Converter

Manufacturer: Richtek

Overview: RT6212A/B 2A, 18V, 500kHz, ACOTTM Step-Down Converter General.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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.
