Overview
AF2304 300KHZ, PFM Control, Synchronous Step-Up DC-DC Converter General Description 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 to prevent it from being damaged.
Features  External parts: Coil, Capacitor  Output voltage: Settable to between 2.
