Battery ic refers to the pulse width control integration of the switching power supply, and the power supply depends on it to adjust the stability of the output voltage and current. With the development of electronic technology, especially the current popularity of portable products and the promotion of energy saving and environmental protection, power ics are playing a more and more important role.

A few years ago, power ics were only integrated voltage regulators and DC\/DC converters, but now power ics cover a lot of things, including DC\/DC, LDO (low-voltage differential linear regulator), battery charge and discharge management, PWM controller, Reset, PFC (power factor correction), energy saving control, power MOSEFT, and more.
