MM3333XN, Step-up DC-DC Converter IC

MITSUMI Step-up DC-DC Converter IC MM3333XN Step-up DC-DC Converter IC Monolithic IC MM3333XN Outline This IC is a step-up DC-DC converter with automatic PWM/PFM switching function.

A step-up DC-DC converter can be configured by using only coil, capacitor, and diode as external components.

It is optimal for applications for mobile equipment that will need high efﬁciency due to characteristics of small package or low current consumption.

Also with an automatic PWM/PFM switching function, decre
