RT8251

5A, 24V, 570kHz Step-Down Converter

General Description

Features

^zWide Operating Input Voltage Range : 4.75V to 24V

^zAdjustable Output Voltage Range : 0.8V to 15V

^zOutput Current up to 5A

The RT8251 is a monolithic step-down switch mode

converter with a built-in internal power MOSFET. It achieves

5A 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.

^z25μA Low Shutdown Current

^zInternal Power MOSFET : 70mΩ

^zHigh Efficiency up to 95%

^z570kHz Fixed Switching Frequency

^zStable with Low ESR Output Ceramic Capacitors

^zThermal Shutdown Protection

The RT8251 provides protection functions such as

cycle-by-cycle current limiting and thermal shutdown. In

shutdown mode, the regulator draws 25μA of supply

current. Programmable soft-start minimizes the inrush

supply current and the output overshoot at initial startup.

The RT8251 requires a minimum number of external

components. The RT8251 is available in WQFN-16L 3x3

and SOP-8 (Exposed Pad) packages.

^zCycle-By-Cycle Over Current Protection

^zRoHS Compliant and Halogen Free

Applications

z Distributed Power Systems

z Battery Charger

z DSL Modems

Pin Configurations

z Pre-regulator for Linear Regulators
