PR 4404 – LED-Treiber, Konstantstromregler, SO-8

Low Voltage Boost Driver for 0,5 / 1,0 W Power-LEDsThe PR4404 is a step-up converter for white LEDs, operating with single battery cellsupply (1.2/1.5V) at up to 150mA LED current or dual cell supply (2.4/3.0V) at up to300mA LED current. A minimum part count allows compact and cost-efficient solutions.The converter can be switched on and off with a logic signal, which is useful e.g. for PWMcontrol, timer circuits etc.
