LM1770 Low-Voltage SOT-23 Synchronous Buck Controller

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 compensation components, allowing minimal component count and board space. It also incorporates a unique input feed-forward to maintain a co.
