LOW NOISE, REGULATED

CHARGE PUMP DC/DC

CONVERTERS

DESCRIPTION

The UTC L5200-xx series are low noise, constant frequency

charge pump DC/DC converters and designed to increase efficiency

input with up to 100mA of output current. Low external parts counts

battery-powered applications.

A charge-pump architecture maintains constant switching

frequency to zero load and reduces both output and input ripple. The

UTC L5200-xx series have thermal shutdown capability to escape

the device damaged from a continuous short-circuit. With built-in

start-up. High switching frequency enables the use of small ceramic

capacitors. A low-current shutdown feature disconnects the load from

The L5200-ADJ is available in MSOP-8 package and

L5200-fixed

in SOT-26 and TSOT-26 package.
