LM5116MHX/NOPB TI DC DC Switching Controllers

The LM5116 is a wide-voltage-range buck controller for step-down converters, operating from 6V to 100V input and driving external MOSFETs for high-current output. It features Emulated Current Mode (ECM) control for stable operation without requiring current sense resistor, providing fast transient response and cycle-by-cycle current limiting. The device includes high-voltage bias regulator, programmable switching frequency up to 1MHz, and soft-start capability. Built-in protection includes thermal shutdown and voltage monitoring. Selection is ideal for rugged industrial and telecom power supplies requiring wide input voltage tolerance. Applications include 48V telecom power systems, 24V industrial automation, automotive 12V/24V battery systems, and off-line power supplies requiring high-voltage step-down conversion with robust performance.
