Advance Information

Dual Low Dropout Voltage

LED Driver/Current Source

This device is designed to replace switching regulators for driving

LEDs in low voltage DC battery applications (up to 6 V). Its unique

integrated circuit design provides low dropout voltage (less than

200 mV), which makes it ideal for battery applications where voltage

overhead is limited. An external resistor allows the circuit designer to

set the LED current for different applications needs. The device is

packaged in a small surface mount leadless package (DFN8), which

results in a significant reduction of both system cost and board space.
