TPS5103IDBR TI Power Management IC | 20-SSOP | Dual Synchronous Buck Controller

Product Overview

The TPS5103IDBR from Texas Instruments is a dual synchronous buck controller IC designed for high-efficiency, low-voltage power conversion. It integrates two independent PWM controllers with adaptive dead-time control, making it ideal for multi-rail systems. Housed in a compact 20-pin SSOP package, it operates over a wide input voltage range of 4.5V to 28V and delivers adjustable output voltages down to 0.9V. The device features programmable switching frequency up to 1MHz, allowing for small external components and reduced board space.
