TPS54616PWPR – TEXAS INSTRUMENTS

The TPS54616PWPR is a 6A synchronous step-down converter from Texas Instruments, packaged in a compact 20-pin HTSSOP (PWPR) surface-mount format. It operates from a wide input voltage range of 4.5V to 18V, efficiently generating a precisely regulated output voltage. The device features a programmable output voltage via an external resistor divider, typically ranging from 0.8V to 5.5V. Internal compensation simplifies design, eliminating the need for external components for most applications._x000D_
