LM25117QPMH/NOPB Information

General Description

The LM25117QPMH/NOPB is a highly versatile synchronous buck controller designed for step-down regulator applications in various high voltage or fluctuating input supply scenarios. It utilizes current mode control with an emulated current ramp, offering benefits such as line feed-forward, cycle-by-cycle current limiting, and easy loop compensation. The programmable operating frequency range is from 50 kHz to 750 kHz, providing flexibility for different application demands

Key Features

Flexible bias supply options
Sychronizable clock frequency selection
Configurable output voltage levels
