LED DRIVER PR4401/PR4402 0.9V Boost Driver for White LEDs PR4401/4402 Requires Only One External Component The PR4401 and PR4402* are single cell step-up converters for white LEDs operating from a supply voltage of less than 0.9V. Only one external inductor is needed for operation of a white LED. PR4401 is recommended for mean LED currents of up to 20mA, PR4402 for up to 40mA. This makes PR4401 and PR4402 ideal for use in low-cost or small-sized applications such as LED flashlights or LCD backlighting for portable devices. Features • • • • minimum startup voltage 0.9V 200/250mA peak output current only one external component required battery deep discharge protection Applications • Small-sized LED torches • LCD backlighting • LED indicator lights Typical Application Vbat =1.2V or 1.
