Overview

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.

Key Features

minimum startup voltage 0.9V 200/250mA peak output current only one external component required battery deep discharge protection.
