Datasheet Summary
LED DRIVER PR4401/PR4402
0.9V Boost Driver for White LEDs PR4401/4402
Requires Only One External ponent
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 remended 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.
