AP9235
General Description
AP9235 is DC/DC step-up converter that deliver 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 AP9235 is ideal for driving up to eight
white LEDs in series or up to 30V.
