CMOS Switching Regulator (PWM controlled) MM3005~MM3010 MITSUMI Description of Operation The MM3005 series are pulse width modulation type DC/DC converters. 1: PWM control uses load to change the duty ratio automatically from 0 ~ 83%. 2: A built-in soft start circuit softens the current inrush at start-up. 3: Power OFF pin: Stops or starts voltage rise operation. When the power OFF pin is at low level the internal circuits all stop operating and consumption current is greatly reduced. Note that the power OFF pin structure is open and unstable, so please be sure not to use it open. Further, do not impress voltage of 0.3 ~ 0.75V, as this causes consumption current to increase. When not using the power OFF pin, please connect it to the VOUT pin. Power off pin Operating condition H ON L OFF Open Irregular Application Circuits When used as voltage drop DC-DC converter.
