XC6371/72C501PR
NOTE: Unless otherwise stated, connect CE to V
*1: The Schottky diode (SD) must be type MA735, with reverse current (I
*2: "Supply Current 1" is the supply current while the oscillator is continuously oscillating. In actual operation the oscillator periodically
*3: When PWM operates at PWM Mode.
*4: When PFM operates at PFM Mode.(XC6372C)
