0 SMALL PACKAGE PFM CONTROL STEP-UP SWITCHING REGULATOR S-8321/8322 Series The S-8321/8322 Series is a CMOS PFM-control step-up switching regulator which mainly consists of a reference voltage source, an oscillation circuit, a power MOS FET, and a comparator.
The new method PFM control circuit automatically switches the duty ratio according to load, offering products of low ripple over a wide range, high efficiency, high output current.
A step-up switching regulator is constructed by externally connecting only a coil, a capacitor and a diode to the S-8321/8322 Series.
This feature, along with its small package and low current consumption, makes the S-8321/8322 Series ideal for the po...
