NCV612SQ50T1 Application Field and Working Principle

NCV612SQ50T1 is a kind of linear voltage regulator that belongs to Power Management Integrated Circuit (PMIC). It is designed to be low consumption, wide temperature range, low dropout Linear voltage Regulator. This article will illustrate the application field and working principle of NCV612SQ50T1.

Application Field

NCV612SQ50T1 is widely applied in applications such as notebook computers, networking devices, and other wireless communications. Its advantages include low quiescent current and low dropout voltage. It is also a tiny device, with the size of only 4.5mm×3.8mm and 0.6mm height.NCV612SQ50T1’s heat resistant ability is also quite remarkable. It contains a thermal sensing circuit that can detect temperature range as wide as -40 to 125 degrees Celsius, which makes it suitable for various environments.

Working Principle

NCV612SQ50T1 provides two stable outputs: Vout and Vref. The Vout can be set between 0.8V to 5.5V and is adjustable. There is also a built-in high performance error amplifier that can adjust Vout gain from 0V to 0.1V.Essentially, the NCV612SQ50T1 uses its error amplifier to compare the output voltage and reference voltage. The transistor will adjust to reduce the impedance of the load and maintain the voltage output at a steady level.The linear regulator also has a built-in Power Good (PG) Output, which reflects its working status. When the output power is above certain level, the output will be logic high, and if not, it will be logic low.

Conclusion

In conclusion, NCV612SQ50T1 is designed to provide low-consumption, wide temperature range. It is applicable to notebook computers, networking devices, and other wireless communications. It can output two different voltage levels, Vout(0.8V to 5.5V) and Vref (0.1V). Finally, its Power Good output can indicate its working status.
