Texas Instruments LM27951SDX is a versatile LED driver IC designed for backlight applications. This device integrates a 4-output DC-DC switched capacitor (charge pump) regulator, enabling efficient voltage conversion for driving multiple LED channels. Featuring PWM dimming capability, the LM27951SDX allows for precise control of LED brightness with a 30mA output current per channel.
The internal switch functionality and a 750kHz switching frequency contribute to its compact design and efficient operation. The LM27951SDX supports an output voltage range of 2.5V to 3.9V, with supply voltage requirements between 2.8V and 5.5V. Supplied in a 14-WSON (4x3) package on tape and reel, this component is suitable for surface mount assembly. Its operating temperature range is -40°C to 85°C.
