AB - Based on PSM (pulse skip modulation) mode, this paper analyzes and optimizes the system, designs a low-power switching power supply chip, and integrates the high-voltage power MOSFET switch and power controller in one device. Different from the traditional PWM (pulse width modulator) controller, the output voltage is regulated by simple on / off control without loop compensation. The controller consists of oscillator, feedback circuit, 5.8V regulator, bypass pin under voltage circuit, over temperature protection, frequency jitter, current limiting circuit and leading edge blanking of integrated 700V power MOSFET. The chip can be applied to mobile phones, digital cameras, and chargers of low-power electrical appliances, etc.
