SY22146A is 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 SY22146A is ideal for driving up to eight white LEDs in series or up to 30V.
