XC9107, XC9106, Step-Up DC/DC Converters

XC9106/XC9107 Series PWM Control, PWM/PFM Switching Control, Step-Up DC/DC Converters, Externally Applied Vref ETR04005-006a *GENERAL DESCRIPTIO

Features

* Input Voltage : 0.9V ~ 10V Power Supply Voltage Range : 1.8V~10.0V and more than Vref+0.7V VREF Input Range : 0.8V~2.5V (±2.0%) Output Voltage : Vref x external split resistor ratio VOUT=Vref x (RFB1+RFB2)/RFB2 Oscillation Frequency : 300kHz, 100kHz (±15%) Output Current : More than 30m

Applications

* that need to vary voltage, such as LCD power supply for PDA.
Output will be stable no matter which load capacitors are used but if a low ESR capacitor is used, RSENSE of about 0.1Ω will be required and phase compensation will be achieved.
This makes the use of ceramic capacitors much easier, and a
