The XC9106 / 07 series are step-up DC/DC controller ICs with an externally applied reference voltage (Vref). Output voltage will be set with external resistors (RFB1 and 2) and Vref value. The series make it easy to control output voltage externally and are suited to software-controlled DC/DC converters.
The document details the Torex XC9106/07 series, which are step-up DC/DC controller ICs with an externally applied reference voltage (Vref). The XC9106 series utilizes PWM control, while the XC9107 series supports automatic switching between PWM and PFM modes for high efficiency across light to large loads. These ICs are designed for applications such as LCD power supplies, PDAs, cellular phones, and portable audio systems. This manual is written in Chinese.
