RT8299

3A, 24V, 500kHz Synchronous Step-Down Converter

Features

General Description

^z3V to 24V Input Voltage Range

The RT8299 is a high efficiency, monolithic synchronous

step-downDC/DC converter with internal power MOSFETs.

It achieves 3A of continuous output current over a wide

input supply range from 3V to 24V with excellent load and

line regulation. Current mode operation provides fast

transient response and eases loop stabilization. Cycle-

by-cycle current limit provides protection against shorted

outputs and soft-start eliminates input current surge during

start-up. Thermal shutdown provides reliable, fault tolerant

operation. The low current shutdown mode provides output

disconnection, enabling easy power management in battery

powered systems.
