... Step-Up DC/DC Converters, Externally Applied Vref ■GENERAL DESCRIPTION The XC9106 / XC9107 series are step-up DC/DC controller ICs with an externally applied reference voltage (Vref). Output voltage will be set with external resistors (R voltage externally and are suited to software applications that need to vary voltage, such as LCD power supply for PDA. ...

... EXT pin's ON time so that it doesn't increase more than is necessary. The XC9106/9107 series alters soft start times by the setting value of reference voltage in order to protect against voltage overshoot and also to protect against inrush current. Please determine soft start time by the formula equation. ...

... Use of Ceramic Capacitor CL> The circuit of the XC9106/9107 series is organized by a specialized circuit, which reenacts negative feedback of both voltage and current. Also by insertion of approximately 100mΩ low and inexpensive sense resistor as current sense, a high degree of stability is possible even using a ceramic capacitor, a condition, which used to be difficult to achieve. Compared to a tantalum condenser, because the series can be operated in a very small capacity suited to use of the ceramic capacitor, which is cheap and small ...
