1
The UTC L5200-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 ~ VOUT
input with up to 100mA of output current. Low external parts counts
(one flying capacitor and two small bypass capacitors at VIN and
VOUT) make the UTC L5200-xx series ideally suited for small,
battery-powered applications.

TSOT-26
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
soft-start circuitry to prevents excessive current flow at VIN during
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: L5200L
VIN and reduces quiescent current to <1µA.
The L5200-ADJ is available in MSOP-8 package and
L5200-fixed in SOT-26 and TSOT-26 package.
