LM1770 Overview
The LM1770 is an efficient synchronous buck switching controller in a tiny SOT-23 package. The constant on-time control scheme provides a simple design free of pensation ponents, allowing minimal ponent count and board space. It also incorporates a unique input feed-forward to maintain a constant frequency independent of the input voltage.
