  • Product introduction

The TPS54550 features a 4.5V to 20V input, 5V synchronous buck converter driven by a low-side FET gate

illustrate

 

The TPS54550 is a medium output current synchronous step-down PWM converter with integrated high-side MOSFETs and a low-side gate to drive external MOSFETs. Features include a high-performance voltage error amplifier that enables transient conditions and selects output filter inductors and capacitors for maximum flexibility. The TPS54550 has an undervoltage latching circuit that prevents start-up until the input voltage reaches 4.5 volts; A slow-start circuit to limit inrush current, and a power good output indicate a valid output condition. The synchronization function is not configured as input or output to facilitate 180° out-of-phase synchronization.

The TPS54550 device is available in a thermally enhanced 16-pin TSSOP (public service) PowerPAD™ package.
