LM5642MTC/NOPB TI Dual Synchronous Buck Controller | 28-TSSOP | 4.5V-36V, 2 Outputs

Product Overview

The LM5642MTC/NOPB is a high-performance dual synchronous buck controller from Texas Instruments, designed for efficient step-down DC-DC conversion. It operates over a wide input voltage range of 4.5V to 36V and provides two independent outputs with adjustable output voltage down to 0.8V. The device features current-mode control for excellent line and load regulation, and includes programmable soft-start, overcurrent protection, and thermal shutdown. Housed in a compact 28-pin TSSOP package, it is ideal for space-constrained applications requiring high efficiency and reliability.
