RT8288A

4A, 21V 500kHz Synchronous Step-Down Converter

General Description

Features

^z4A Output Current

The RT8288A is a synchronous step-down regulator with

an internal power MOSFET. It achieves 4A of continuous

output current over a wide input supply range with excellent

load and line regulation. Current mode operation provides

fast transient response and eases loop stabilization.

^zInternal Soft-Start

^z120mΩ/40mΩ Internal Power MOSFET Switch

^zInternal Compensation Minimizes External Parts

Count

^zFixed 500kHz Frequency

Fault condition protection includes cycle-by-cycle current

limiting and thermal shutdown. An internal soft-start

minimizes external parts count and internal compensation

circuitry.

^zThermal Shutdown Protection

^zCycle-by-Cycle Over Current Protection

^zWide 4.5V to 21V Operating Input Range

^zAdjustable Output from 0.808V to 15V

^zAvailable in an SOP-8 (Exposed Pad) Package

^zRoHS Compliant and Halogen Free

The RT8288A requires a minimal number of readily

available external components, providing a compact

solution.

Applications

z Distributive Power Systems
