NMP1K2-#EEH#C-02 AC/DC converter is a highly integrated digital switching power supply, which comprises a DC/DC controller, an MOSFET switch, and a power output stage. It is designed to promise high efficiency, low ripple, and low electromagnetic interference (EMI) in low power and low voltage applications.

The device has an on-board control integrated circuit (IC) with pulse width modulation (PWM) generator, over-voltage and over-temperature protection, and various conditional operation timing controlling features.

NMP1K2-#EEH#C-02 converter can be used in different application fields such as consumer electronics, industrial systems, and telecom systems. It has been proven to be robust and reliable in providing a steady output voltage over a wide range of temperatures and environmental conditions.

The device operates with an input voltage range from 80 to 260 V AC or 200 to 400 V DC and offers a range of output voltages ranging from 3.3 to 5.0 V DC. It is rated for a maximum output power of 1W, and a peak current of 3A with a standby current of 100uA. The device also features protection against over-voltage, over-temperature, and short-circuit conditions.

In terms of working principle, the NPM1K2-#EEH#C-02 AC/DC converter works by first rectifying the input AC or DC voltage into a DC voltage, which is then regulated and distributed by the internal control circuit. The internal circuit uses a pulse width modulator to control the output voltage by comparing the required output voltage with a reference voltage. This regulation is done by controlling the duty cycle of the output switch, which is connected to the output stage. The output stage features topology that consists of a two-stage active clamp flyback converter. This topology is reliable as well as efficient, allowing both high power and small size. The output switch operates according to the PWM signal; when the input voltage is off, the switch will be off as well, and the output voltage will be low, which is good for preventing overload or short circuit.

In summary, NMP1K2-#EEH#C-02 AC/DC converter is a highly integrated digital switching power supply that provides high efficiency, low ripple, and low electromagnetic interference in low power and low voltage applications. It is highly reliable, and can be used in various different application fields. The device operates according to a pulse width modulator, which will regulate the output voltage by controlling the duty cycle of the output switch, and provides over-voltage, over-temperature, and short-circuit protection.
