GENERAL DESCRIPTION

The XC9103/9104/9105 series are PWM, PWM/PFM auto switching/manual switching controlled multi-functional step-up DC/DC converter controllers.

Output will be stable no matter which load capacitors are used but should a low ESR capacitor be used, RSENSE of about 0.1? 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.
