Introduction

The CMPWR101R, or Compex Power Device, is a Linear Voltage Regulator (LVR) manufactured by Compex, an American–based semiconductor company. It is a low-cost, highly efficient voltage regulator with an operating voltage range of 0.9 V to 36 V and a power output of 10 A. The CMPWR101R is designed for use in a variety of applications, such as automotive, industrial, and consumer electronics. This document will discuss the application fields and working principles of the CMPWR101R.

Application Fields

The CMPWR101R can be used in a variety of applications such as providing the regulated power to automotive electronics, industrial systems, and consumer electronics. For automotive applications, the CMPWR101R provides regulated power for automobile components such as sensors, solenoids, and motors. In industrial systems, the CMPWR101R can be used to provide regulated power supply for high-power air conditioners, CNC machines, and other industrial components. For consumer electronic devices, the CMPWR101R can be used to regulate the voltage of televisions, audio/video systems, and game consoles.

Working Principle

The CMPWR101R is a linear voltage regulator, which means it preserves the power supply voltage and limits the voltage to the output current. It does this by using pass transistors with a feedback circuit to monitor and adjust the power supply voltage. When the load increases or decreases on the output side, the feedback circuit senses it and adjusts the voltage to match the load. The CMPWR101R features a totem-pole topology with a low standby current of 3 μA and offers a power-on reset function to protect the power supply from out of tolerance conditions.

Conclusion

The CMPWR101R is a Linear Voltage Regulator that is used in a variety of applications, ranging from automotive components to consumer electronic devices. It is designed for low cost and high efficiency, with an operating voltage of 0.9 V to 36V and a maximum current of 10A, and has a totem-pole topology with a low standby current of 3μA. It also offers a Power On Reset function to protect the power supply from out of tolerance conditions.
