TPS9103PWR TI Power Management IC | 20-TSSOP | 4.5V-18V Input, 3A Output

Product Overview

The TPS9103PWR from Texas Instruments is a high-performance, synchronous step-down (buck) converter designed for a wide range of power management applications. Housed in a compact 20-pin TSSOP package, this device integrates a high-side and low-side MOSFET to deliver up to 3A of continuous output current. With an input voltage range of 4.5V to 18V, it is ideal for systems powered by 5V, 12V, or intermediate bus voltages. The TPS9103PWR features a fixed switching frequency of 500kHz, enabling small external components and efficient power conversion.
