TPS53661RSBT TI Power Management IC | 40-WQFN (5x5) | Dual Output, PMBus

Product Overview

The TPS53661RSBT from Texas Instruments is a highly integrated, dual-output, step-down (buck) 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 its 40-WQFN (5x5) package, it offers a compact solution for space-constrained designs.
