TPS54240DGQR – TEXAS INSTRUMENTS

The TPS54240DGQR is a 40V, 2A synchronous step-down converter from Texas Instruments, packaged in a compact 16-pin QFN (4x4mm) package. It utilizes a hysteretic control architecture for fast transient response and minimal output voltage ripple, crucial for applications demanding tight regulation. Operating from an input voltage range of 4.5V to 40V, it efficiently regulates output voltages from 0.8V to 36V, configurable via an external resistor divider. Its internal 2A switch current limit provides robust short-circuit protection. The device boasts high efficiency, typically exceeding 90% across a wide load range, minimizing power loss and heat dissipation. Internal features include soft-start, enabling controlled inrush current limiting, and an enable pin for power sequencing control._x000D_
