LM2753SDX/NOPB

LM2753SDX/NOPB Description

The LM2753SDX/NOPB from Texas Instruments is a high-efficiency DC-DC regulator designed for driving LEDs in camera flash applications. This switched capacitor (charge pump) topology device integrates an internal switch, enabling compact designs with minimal external components. Operating within a 3V to 5.5V input range, it delivers a regulated output of 4.75V to 5.25V at up to 400mA for flash LEDs. With a 725kHz switching frequency, it ensures low noise and high efficiency, while PWM dimming provides precise brightness control. Packaged in a 10-pin SON (Small Outline No-Lead) and available in Tape & Reel (TR), it is ideal for space-constrained applications.
