Product Description

Step-up DC/DC Controller with Vref input

The XC9106~07 series are step-up DC/DC controller ICs with an externally applied reference voltage. The output voltage is set-up using two external resistors and the Vref value. This makes it easy to control the output voltage externally, using software. The XC9106/07 is ideally suited to applications that need to vary voltage, such as the power supply for an LCD. The XC9106/07 is designed for use with ceramic capacitors and maintains very low output ripple.
