It is composed of reference voltage generator with automatic temperature compensation function, comparator, duty cycle controlled oscillator, R-S flip-flop and high current output switching circuit. The device can be used as the control core of boost converter, buck converter and reverse converter, and the DC\/DC converter formed by it only uses a small number of external components. It is mainly used in microprocessor (MPU) or MCU based systems.
