Product Description
LM25117PMHX Integrated Circuit Chip Wide Input Range Synchronous Buck Controller With Analog Current Monitor
Product Description
The LM25117PMHX is a synchronous buck controller designed for step-down regulator applications from high voltage or widely varying input supplies. Utilizing current mode control with an emulated current ramp, it provides inherent line feed-forward, cycle-by-cycle current limiting, and simplified loop compensation. The emulated control ramp enhances noise immunity, enabling reliable control of very small duty cycles required in high input voltage applications.
