LM1770 Datasheet (Texas Instruments) - Low-Voltage SOT-23 Synchronous Buck Controller

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
