It is capable of operating across the 0.35V to 43V input range". All of these features provide customers with reliable and stable performance.

Application FieldXC9142B50DMR-G is a very versatile product. It is suitable for many applications such as consumer electronics, medical electronics and telecommunication equipment. In consumer electronics, it is used in television and other computer peripherals such as printers and scanners. In medical electronics, it is used in monitoring and control systems. In telecommunication equipment, it is used in base stations, routers and switches. It is also used in industrial equipment, automotive and aerospace applications.

Working PrincipleThe XC9142B50DMR-G DC-DC switching regulator functions through the use of synchronized switches. It uses two sets of switches- one operates at a higher frequency and the other at a lower frequency. The higher frequency switches control the current through the inductor. The lower frequency switches control the output voltage independently. This is done by connecting the inductor between the input terminal and the output terminal through the high frequency switch. The output voltage is then determined by controlling the duty cycle that the higher frequency switch is on.

The regulator relies on a voltage feedback loop. This loop monitors the output voltage by comparing it to a reference voltage. The output voltage is adjusted by changing the duty cycle of the high frequency switch. This can be done by adjusting the control signal from the voltage feedback loop.

The XC9142B50DMR-G can provide a wide range of current and voltage output for your application needs. It also features adjustable current and voltage limits as well as over temperature protection for improved reliability and performance.

Conclusion
The XC9142B50DMR-G from the PMIC – Voltage Regulators family is a DC-DC switching regulator that is equipped with versatile features such as adjustable output voltage tolerance and current limit settings, output disable, soft start, and preset and adjustable output voltage trimming. It is suitable for many applications such as consumer electronics, medical electronics, telecommunication equipment, industrial equipment, automotive and aerospace. The regulator is capable of providing a wide range of current and voltage output for your application needs by utilizing a synchronized switches system in a voltage feedback loop.
