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.
