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 H L Open Operating condition ON OFF Irregular Application Circuits When used as voltage drop DC-DC converter. MITSUMI MITSUMI CMOS Switching Regulator (PWM controlled) MM3005~MM3010 Characteristics MM3005EN Output voltage3V typ. product Starting output voltage - temperature 1.2 1.0 IOUT=1mA Starting oscillator voltage - temperature 1.0 0.8 VST1 (V) 0.8 0.6 0.4 VST2 (V) 0.6 0.4 0.2 0.2 0.0 -40 -20 0.0 -40 -20 0 20 40 60 80 100 0 20 40 60 80 100 Ta (°C) Ta (°C) Supply current 1 - temperature 50 40 VOUT=Output Voltage 0.95 Supply current 2 - temperature 5 4 VOUT=Output Voltage+0.5 ISS1 (µA) 30 20 10 0 -40 -20 ISS2 (µA) 0 20 40 60 80 100 3 2 1 0 -40 -20 0 20 40 60 80 100 Ta (°C) Ta (°C) Supply current (OFF) - temperature 1.0 0.8 0.6 0.4 0.2 0.0 -40 -20 ON/OFF pin=0V Switch current - temperature 255 200 175 150 125 100 75 50 25 0 -40 -20 VCONT=0.4V 0 20 40 60 80 100 ISW (mA) ISSS (µA) 0 20 40 60 80 100 Ta (°C) Ta (°C) Note: these are typical characteristics. MITSUMI CMOS Switching Regulator (PWM controlled) MM3005~MM3010 Switch transistor leak current - temperature 1.0 0.8 VOUT=VCONT=10V Oscillator frequency - temperature 70 65 60 VOUT=Output Voltage 0.95 fOSC (kHz) 0 20 40 60 80 100 ISWQ (µA) 0.6 0.4 0.2 0.0 -40 -20 55 50 45 40 35 30 -40 -20 0 20 40 60 80 100 Ta (°C) Ta (°C) Maximum duty cycle - temperature 100 90 80 VOUT=Output Voltage 0.95 ON/OFF Pin input voltage (VSH) - temperature VOUT=Output Voltage 0.95 The oscillation waveform of CONT PIN is measured. 1.0 0.8 MaxDuty (%) VSH (V) 0 20 40 60 80 100 70 60 50 -40 -20 0.6 0.4 0.2 Ta (°C) 0.0 -40 -20 0 20 40 60 80 100 Ta (°C) ON/OFF Pin input voltage (VSL) - temperature VOUT=Output Voltage 0.95 The oscillation stop of CONT PIN is measured.
