TPS54383PWPR TI Dual Buck Converter | 14-HTSSOP | 4.5V-28V Input, 3A Output

Product Overview

The TPS54383PWPR from Texas Instruments is a dual-output, synchronous buck converter with integrated MOSFETs. It operates from a 4.5V to 28V input supply and provides two independent output voltages adjustable from 0.8V to 90% of input voltage. Each output can deliver up to 3A continuous current. The device is housed in a compact 14-pin HTSSOP package with PowerPAD for enhanced thermal performance. It features fixed 300kHz or 600kHz switching frequency, internal compensation, and a wide range of protection features including overcurrent, overvoltage, and thermal shutdown.
