产品概览
The TPS40009DGQR from Texas Instruments is a low-input-voltage synchronous buck controller designed for high-efficiency DC-DC conversion from input voltages as low as 2.25 V. Packaged in a 10-pin MSOP (DGS) package, it integrates a 600-kHz fixed-frequency voltage-mode controller with adaptive gate drivers for N-channel MOSFETs, targeting point-of-load applications.
