Description of Operation

CMOS Switching Regulator (PWM controlled) MM3005~MM3010

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.
