XC651A series

      The XC651A series has the following features including CMOS Low Power Consumption ;PFM Controlled, Step-Up DC/DC Converter;5 Level Window Comparator;Voltage Detector × 2 ( Independent Power Supply );TSSOP-16 Package.
      The XC651A series are step-up DC/DC converter and multi voltage detector IC s. CMOS processes and laser trimming technology provide high accuracy and low power consumption. The XC651A comprises of a PFM controlled step-up DC/DC converter, a voltage detector with 4 x 5 level window comparators built-in, plus 2 other voltage detectors. The step-up DC/DC converter's EN pin ( chip enable ) provides power consumption savings when the step-up operations are not operating ( stand-by mode ). The series is available in a small TSSOP-16 package.The set-up voltage of the 5 level window comparator cannot be freely set-up due to the limitations of the circuit.Please also note that the set-up voltage range of MWVD1 is 1.0V ~ 1.8V.note that the above is a sample part number and that actual part numbers will differ,Unless indicated, connect EN to VOUT, VIN=Output Voltage x 0.6, IOUT=10mA.
