Everyone is familiar with the word chip, but there are many kinds of chips. Today, let's take a look at power management chips. The main component of a power management semiconductor is a power management IC. What is a power management chip? Commonly used power management chips can be roughly summarized as the following eight.
1.AC/DC modulation IC. It includes a low voltage control circuit and a high voltage switching transistor.
2.DC/DC modulation IC. Includes boost/step-down regulators and charge pumps.
3.PFC premodulation IC control power factor. Provide power input circuit with power factor correction function. http://www.ic-jfsd.com/
4. Pulse modulation or pulse modulation PWM/PFM control IC Pulse frequency modulation and/or pulse width modulation controllers are used to drive external switches.
5. Linear modulation IC(such as linear low voltage step-down LDO, etc.).
6. Battery charging and IC management. Including battery charging, protection and power display IC, as well as intelligent battery IC for battery data communication.
7. Hot swapboard control IC(exempt from the influence of inserting or pulling out another interface from the working system).
8 MOSFET or IGBT switching function IC.
These are the eight common categories of power management chips. Because of the wide application of power management chip, the development of power management chip is of great significance to improve the performance of the whole machine.
