RT8271

2A, 24V, 1.2MHz Step-Down Converter

General Description

Features

^zWide Operating Input Range : 4.75V to 24V

^zAdjustable Output Voltage Range : 0.92V to 16V

^zOutput Current up to 2A

The RT8271 is a high voltage buck converter that can

support the input voltage range from 4.75V to 24V and the

output current can be up to 2A. Current Mode operation

provides fast transient response and eases loop

stabilization. The RT8271 also provides adjustable soft-

start to be a flexible solution for customers.

^z22μA Low Shutdown Current

^zPower MOSFET : 0.18Ω

^zHigh Efficiency up to 92%

^z1.2MHz Fixed Switching Frequency

^zStable with Low ESR Output Ceramic Capacitors

^zProgrammable Soft-Start

The chip provides protection functions such as cycle-by-

cycle current limiting and thermal shutdown protection.

In shutdown mode, the regulator draws 22μA of supply

current. The RT8271 is available in the SOP-8 and

MSOP-10 (Exposed Pad) surface mount package.

^zThermal Shutdown Protection

^zCycle-By-Cycle Over Current Protection

^zRoHS Compliant and Halogen Free
