DESCRIPTION
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 ~ 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.
SOT-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 VIN and reduces quiescent current to <1µA.
The L5200-ADJ is available in MSOP-8 package and
L5200-fixed in SOT-26 package.
