TPS59641RSLR TI Power Management IC | 48-VQFN (6x6) | 4.5V-28V Input, Dual Output

Product Overview

The TPS59641RSLR from Texas Instruments is a highly integrated, dual-output synchronous buck controller designed for point-of-load (POL) applications. It operates from a 4.5V to 28V input supply and provides two independent output voltages as low as 0.6V. The device features D-CAP+™ mode control for fast transient response and excellent load regulation. Housed in a compact 48-pin VQFN (6x6 mm) package, it is ideal for space-constrained designs in networking, telecom, and industrial systems.
