SY7200
30V High Current Boost LED Driver
General Description
SY7200 is a DC/DC step-up converter that delivers an
accurate constant current for driving LEDs. Operation
at a fixed switching frequency of 1MHz allows the
device to be used with small value external ceramic
capacitors and inductor. LEDs connected in series are
driven with a regulated current set by the external
resistor. The SY7200 is ideal for driving up to eight
white LEDs in series or up to 30V.
