CMOS IC

LOW NOISE, REGULATED

CHARGE PUMP DC/DC

CONVERTERS

MSOP-8

DESCRIPTION

The UTC L5201-xx series are low noise, constant frequency

SOT-26

charge pump DC/DC converters and designed to increase efficiency

in white LED application. The operating voltage range is 2.7V ~ V_OUT

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

(one flying capacitor and two small bypass capacitors at V_INand

V_OUT) make the UTC L5201-xx series ideally suited for small,

battery-powered applications.

TSOT-26

charge-pump architecture maintains constant switching

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

UTC L5201-xx series have thermal shutdown capability to escape

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

soft-start circuitry to prevents excessive current flow at V_INduring

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

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

*Pb-free plating product number: L5201L

V_INand reduces quiescent current to <1µA.

The L5201-ADJ is available in MSOP-8 package and

L5201-fixed in SOT-26 and TSOT-26 package.
