AF2304 Datasheet (AFSEMI) - Synchronous Step-Up DC-DC Converter

AF2304, Synchronous Step-Up DC-DC Converter

The AF2304 Series is a Synchronous step-up DC/DC Converter with PFM Control.

With the AF2304 Series, a step-up switching DC/DC converter can be configured by using an external coil, capacitor.

The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit
