.. LM1771 Low-Voltage Synchronous Buck Controller with Precision Enable and No External pensation June 2006 LM1771 Low-Voltage Synchronous Buck Controller with Precision Enable and No External pensation General Description The LM1771 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. The LM1771 also incorporates a unique input feed-forward to maintain a constant frequency...
