LOW NOISE, REGULATED
CHARGE PUMP DC/DC
CONVERTERS
DESCRIPTION
The UTC L5201-xx series are low noise, constant frequency
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 L5201-xx series ideally suited for small,
battery-powered applications.
A 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 VIN during
start-up. High switching frequency enables the use of small ceramic
capacitors. A low-current shutdown feature disconnects the load from
VIN and reduces quiescent current to <1A.
The L5201-ADJ is available in MSOP-8 package and
L5201-fixed
in SOT-26 and TSOT-26 package.
