NCP81203MNTXG Application Field and Working Principle

Categorized as PMIC - Voltage Regulators - Special Purpose

NCP81203MNTXG is a voltage controller for high temperature application, which is categorized under Power Management Integrated Circuits (PMICs) - Voltage Regulators - Special Purpose. This device is for applications requiring supply superstabilization, overcurrent protection, overtemperature protection, overvoltage protection and supply fault reporting. It can be used in such applications as high-side current monitoring, power supply fault reporting, LCD bias generation, overcurrent/overvoltage protection, and N-channel MOSFETs driven by pulse width modulation.

In terms of its working principle, the NCP81203MNTXG is a digital system of power regulation which includes a digital voltage regulator and a driver circuit. The digital voltage regulator is made up of a duty cycle modulated PWM controller and a power switch such as a MOSFET. The main functions of the digital voltage regulator are to maintain the regulated voltage and the regulated current, to limit the power dissipation, to provide fault protection, and to provide overvoltage protection. On the other hand, the driver circuit is responsible for driving the power switch.

The NCP81203MNTXG device supports two types of supply super-stabilization, which are synchronized and asynchronous. In the synchronous super-stabilization, the power switch is operated synchronously with the PWM controller. On the other hand, in the asynchronous super-stabilization, the power switch is operated asynchronously with the PWM controller. Furthermore, the device can operate in either open-loop mode or closed-loop mode, which is achieved by selecting the appropriate mode pin configuration.

In terms of its features, the NCP81203MNTXG device is supposed to operate in a wide variety of applications, as it can withstand high temperature environments and has excellent noise immunity. The device is also designed for low power consumption, as it has a quiescent current of only 2 mA. Furthermore, it supports a wide range of input and output voltages and provides a single-stage power conversion efficiency of up to 97%.

The NCP81203MNTXG device can have a wide range of applications, such as battery chargers, laptop power supplies, automotive power systems, white goods and industrial applications. The device is also suitable for the applications requiring simplicity and high performance, such as lighting systems, space modules and off-grid solar systems.

In conclusion, the NCP81203MNTXG is a high temperature voltage controller categorized as a PMIC - Voltage Regulators - Special Purpose. It supports two types of supply super-stabilization, both synchronous and asynchronous. The device is suitable for a wide range of applications, such as battery chargers and white goods. It has an excellent noise immunity and a low power consumption, and provides a single-stage power conversion efficiency of up to 97%.
