XC9306B05G0R-G - Synchronous Rectification Buck-Boost DC/DC Converter IC

General Description

The XC9306B05G0R-G is a synchronous buck-boost DC/DC converter IC with built-in FETs.

The circuit topology switches over between buck and boost smoothly based on the relationship of the input voltage and the output voltage which is observed by the internal PWM controller.

XC9306B05G0R-G ETR06003-002 Synchronous Rectification Buck-Boost DC/DC Converter IC ☆GreenOperation Compatible ■GENERAL DESCRIPTION The XC9306B05G0R-G is a synchronous buck-boost DC/DC converter IC with built-in FETs. The circuit topology switches over between buck and boost smoothly based on the relationship of the input voltage and the output voltage which is observed by the internal PWM controller. Due to the internal FETs, the number of external components is reduced. Also, a 6MHz switching frequency enables smaller external components, such as a coil and capacitors, to be used. The input voltage range is 2.5V~5.5V and the output voltage is adjustable from 0.8V to 5.0V by using external resistors since the reference voltage circuit is embedded internally.
