TPS2052BD – TEXAS INSTRUMENTS

The TPS2052BD is a single-channel, synchronous, 4A step-down converter from Texas Instruments, packaged in a compact 16-pin QFN (4x4mm) surface-mount package. It operates from a wide input voltage range of 4.5V to 18V, providing a highly efficient and regulated output voltage. The device features internal compensation, simplifying design and reducing external component count. Its adjustable output voltage, typically ranging from 0.8V to 5.5V, is set via a single external resistor._x000D_
