LM5576MHX/NOPB step-down converter ic
The LM5576MHX/NOPB is a wide-input voltage, adjustable frequency, monolithic buck (step-down) switching regulator from Texas Instruments. Designed for robust and flexible power conversion, it operates from an input supply range of 6V to 75V, making it suitable for applications powered from industrial buses, automotive batteries, or unregulated wall adapters. This device integrates a 75V, 3A N-channel MOSFET and can deliver a regulated output from 1.225V up to the input voltage. Its primary function is to efficiently step down a high, variable DC voltage to a stable, lower DC voltage for powering sensitive digital and analog loads in harsh electrical environments.
LM5576MHX/NOPB Buck Switching Regulator Features
This regulator utilizes an emulated peak-current-mode control architecture, which simplifies loop compensation and provides inherent line feedforward for excellent line transient response. Its switching frequency is adjustable from 50 kHz to 500 kHz via an external resistor, allowing optimization for efficiency or component size. Key features include a precision 1.5% voltage reference, programmable soft-start, and thermal shutdown. It incorporates comprehensive protection functions such as cycle-by-cycle current limit, hiccup mode short-circuit protection, and input undervoltage lockout. Packaged in a thermally enhanced 20-HTSSOP with an exposed pad, it is rated for operation over the industrial junction temperature range of -40°C to +125°C.
