Texas Instruments LM2794BL is a highly integrated LED driver IC featuring a switched capacitor (charge pump) DC-DC regulator topology. This device offers 4 outputs, each capable of delivering up to 20mA, suitable for demanding backlight applications. The LM2794BL supports both analog and PWM dimming, providing granular control over LED brightness. Its internal switch functionality and a switching frequency of 515kHz contribute to efficient operation. Designed for surface mount installation, it is supplied in a compact 14-DSBGA package, presented on tape and reel. Operating within a supply voltage range of 2.7V to 5.5V, with a nominal output voltage of 3.8V, this component is engineered for performance in applications requiring precise LED current regulation.
