LED Driver PR4403 0.9 V Boost Driver PR4403 for White LEDs in Solar Lamps The PR4403 is a single cell step-up converter for white LEDs operating from a single rechargeable cell of 1.2 V supply voltage down to less than 0.9 V. An adjustable light threshold input enables an automatic switching of the LED light, e. g. by an additional light sensor or by the battery charging solar cell itself. Only three external components are required for operation of a white LED. The PR4403 is recommended for mean LED currents of up to 40 mA. This makes PR4403 ideal for use in low-cost or small-sized light applications such as solar LED lamps, LED flashlights or LCD backlighting for portable devices. FEATURES • only one 1.
