■ GENERAL DESCRIPTION
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 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 allows for lower output ripple and reduced PCB area requirements.
Tantalum and electrolytic capacitors can also be used, in which case, RSENSE
becomes unnecessary.
■ FEATURES
