Texas Instruments LM27952SDX is a 4-output DC-DC regulated LED driver IC featuring a switched capacitor (charge pump) topology. This device provides precise PWM dimming control for LED backlighting applications, with an output current capability of 30mA per channel. The switching frequency is 750kHz, and it integrates internal switches for efficient operation. Designed for surface mounting, the LM27952SDX is supplied in a 14-WSON (4x3) package, identified by the 14-WFDFN Exposed Pad designation. Operating within a supply voltage range of 3V to 5.5V, its output voltage can be adjusted between 2.5V and 3.9V. The component is rated for operation across an ambient temperature range of -40°C to 85°C. This device is commonly utilized in display backlighting solutions.
