High Efficiency, 36V 100mA Synchronous Step-Down Converter

General Description

The RT6208 is a high-efficiency, monolithic synchronous

step-down DC/DC converter that can deliver up to

100mA output current from a 4.5V to 36V input supply. It

requires only 25

A typical supply current at no load

while maintaining output voltage regulation. The RT6208

achieves Boundary Conduction Mode (BCM) operation,

low quiescent current and programmable high-side peak

current limit, providing high efficiency over a wide range

of load currents. It also provides soft-start protection to

eliminate input current surge during start-up. The low

current

(3

A) shutdown mode provides output

disconnect,

enabling easy

power

management in

battery-powered systems. The RT6208 is available in a

SOT-23-6, SOT-23-8 and SOP-8 (Exposed Pad, with

power good function) packages.
