Negative voltage management using a FAN8303 buck regulator

Posted: 27 Jan 2010     Print Version  Bookmark and Share

Keywords:buck regulator  negative voltage  FAN8303 regulator 

FAN8303 is a 2A, 370kHz monolithic integrated buck regulator with internal power MOSFETs. It is simple to use and needs minimal external components. This application note describes how to generate negative voltage using FAN8303. It introduces application examples and discusses optimised designs for a buck-boost circuit.

Buck regulators are widely used for higher voltage to lower voltage DC conversion. Likewise, FAN8303 was originally designed for application needing regulated DC voltage, such as STB MCUs and efficient pre-regulators for linear regulators in PC monitor and TV applications.
