TPS53688RSBT TI Power Management IC | 40-WQFN (5x5) | Dual Output, PMBus

Product Overview

The TPS53688RSBT from Texas Instruments is a highly integrated, dual-output, step-down controller with PMBus interface. It is designed for high-current, low-voltage applications requiring precise voltage regulation and fast transient response. The device operates from a 4.5V to 17V input supply and can deliver output voltages as low as 0.25V with ±0.5% accuracy. Housed in a compact 40-WQFN (5x5) package, it is ideal for space-constrained designs.
