LM1770, SOT-23 Synchronous Buck Controller
The LM1770 is an efficient synchronous buck switching controller in a tiny SOT23 package.
The constant on-time control scheme provides a simple design free of compensation components, allowing minimal component count and board space.
It also incorporates a unique input feed-forward to maintain a con
