Datasheet Summary
LED DRIVER PR4404
Low Voltage Boost Driver PR4404 for 0.5W / 1W Power LEDs
The PR4404 is a step-up converter for white LEDs, operating with single battery cell supply (1.2/1.5V) at up to 150mA LED current or dual cell supply (2.4/3.0V) at up to 300mA LED current. A minimum part count allows pact and cost-efficient solutions. The converter can be switched on and off with a logic signal, which is useful e.g. for PWM control, timer circuits etc.
