Step-Up DC/DC Converter MM1331
Step-Up DC/DC Converter (VFF)
Monolithic IC MM1331
Outline
This is a converter IC which steps up the DC input voltage to output a fixed voltage level. Utilizing technology
for low-voltage operation, which is a feature of Mitsumi semiconductor processes, operation is possible
beginning at 0.85V, making this device ideal for the power supply circuits of portable equipment driven by a
single battery.
Under small load currents oscillation is stopped and the charge stored in an externally mounted capacitor is
output in an intermittent oscillation design, to improve the efficiency of operation under light loads.
Features
1. Low-voltage operation possible, 0.85V (no-load)
2. Internal oscillation circuit
3. Intermittent oscillation design for improved light-load efficiency
4. Numerous output voltages available (seven ranks)
