The UTC
L5200-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 ~ V
OUT
input with up to 100mA of output current. Low external parts counts
(one flying capacitor and two small bypass capacitors at V
IN
and
V
OUT
) make the UTC
L5200-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
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 V
IN
during
start-up. High switching frequency enables the use of small ceramic
capacitors. A low-current shutdown feature disconnects the load from
V
IN
and reduces quiescent current to <1μA.
The
L5200-ADJ
is available in MSOP-8 package
L5200-fixed
in SOT-26 and TSOT-26 package.
