NCP130AMX210TCG Application Field and Working Principle

The NCP130AMX210TCG is a linear voltage regulator with multiple outputs commonly used in power management systems. It is a high-performance regulator that offers features such as wide input voltage range and low dropout voltage. The NCP130AMX210TCG is an ideal solution for applications that require a wide range of voltage regulation needs, as it can deliver both steady and reliable operation and precise voltage regulation for up to five outputs.

Applications:

The NCP130AMX210TCG linear voltage regulator is the ideal choice for a variety of applications such as:

• Telecommunications systems
• Consumer electronics
• Industrial control and automation systems
• Automotive systems
• Medical equipment
• Computer peripherals

Features:

The NCP130AMX210TCG linear voltage regulator is a highly efficient component that offers many high-end features, some of which are:

• Wide input voltage range (2.7V to 60V)
• Low dropout voltage (1V typical)
• Low line and load regulation (1% from 0.2V to 60V)
• Programmable over-voltage protection
• Short-circuit protection
• Crossover-current protection
• Thermal shutdown

Operation Modes:

The NCP130AMX210TCG linear voltage regulator operates in two different modes:

• Continuous mode: In this mode, the output voltage is maintained as constant and the device operates until the input voltage drops below the lower limit. When the input voltage rises above the lower limit, the circuit resumes its normal operation.
• Pulsed mode: In this mode, the output voltage is maintained as constant, but the device is switched off when the input voltage drops below the lower limit and then resumed when it rises above the lower limit.

Working Principle:

The NCP130AMX210TCG linear voltage regulator is designed with two main components: the sense resistor and the error amplifier. The sense resistor is responsible for monitoring the output voltage and providing feedback to the error amplifier. The error amplifier regulates the output voltage by comparing it to a reference voltage and controlling the current through the sense resistor.

When the output voltage goes below the reference voltage, the error amplifier sends a signal to the sense resistor to lower its resistance, which in turn causes a decrease in the current flowing through the sense resistor. The decrease in current reduces the voltage drop across the sense resistor, which results in an increase in the output voltage.

On the other hand, when the output voltage rises above the reference voltage, the error amplifier sends a signal to the sense resistor to increase its resistance, which in turn causes an increase in the current flowing through the sense resistor. The increase in current increases the voltage drop across the sense resistor, which results in a decrease in the output voltage.

The NCP130AMX210TCG linear voltage regulator is a highly efficient component designed for a wide range of voltage requirements.
