Richtek RT6213B

Description

The RT6213A/B is a high-efficiency, monolithicsynchronous step-down DC/DC converter that can deliver up to 3A peak output current from a 4.5V to 18V input supply. The RT6213A/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 currentprotection, and thermal shutdown.
