XC9107 series
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.
Features:
- Input Voltage: 0.9V ~ 10.0V
- Output Voltage: 1.8V ~ 30.0V
- VREF input: 0.8V ~ 2.5V
- Switching Frequency: 300KHz, or 100kHz
- Output current: > 30mA
- Standby Current: 1.0μA (max)
