General Description

The RT8253A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply.

The RT8253A's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors.

Cycle by cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start up.
