LM25117PMHE/NOPB TI DC-DC Controller | 20-HTSSOP | Wide Vin, 100% Duty Cycle

Product Overview

The LM25117PMHE/NOPB is a wide input range, synchronous buck controller from Texas Instruments. It is designed for high-efficiency step-down DC-DC conversion in applications requiring a robust and flexible power management solution. The device operates over a 4.5V to 42V input voltage range and can deliver output voltages as low as 0.8V with ±1.5% accuracy. Its 100% duty cycle capability allows for low dropout operation, making it suitable for battery-powered systems. The controller features programmable switching frequency up to 750 kHz, cycle-by-cycle current limiting, and hiccup mode overcurrent protection. Housed in a 20-pin HTSSOP package with exposed pad for thermal dissipation, the LM25117PMHE/NOPB is ideal for industrial, automotive, and telecom power supplies.
