LM1771 Overview
The LM1771 device is an efficient synchronous buck switching controller with a precision enable requiring no external pensation. The constant ON-time control scheme provides a simple design free of pensation ponents, allowing minimal ponent count and board space. The precision enable pin allows flexibility in sequencing multiple rails and setting UVLO.
