NJU7660AM-TE1 integrated power module is a power management integrated circuit (PMIC) regulator, named in the voltage regulator family of DC DC switching regulator. It can AUTO step up, step down, as well as power conversion from an input voltage range to one of the regulated output voltages. More information about NJU7660AM-TE1 can be found in the datasheet.

The application fields of NJU7660AM-TE1 can be found in the datasheet. It is suitable for any laptop, TV, tablet, and other consumer related products, which all need an internal DC-DC converter. As an AC/DC power supply, it reduces the need for an external conversion device, as well as low output ripple, high efficiency, low noise, resulting in improved system power performance, better power security and dynamic response.

The working principle of the NJU7660AM-TE1 module is as follows. The module includes an internal DC/DC power conversion circuit and an internal voltage regulator circuit. The DC motor energization circuit is made up of a rectifier bridge, an electrolytic capacitor and an inductor. The rectifier bridge receives the input AC or DC voltage, the alternating current is the rectified DC voltage, the rectified DC voltage is supplied to the electrolytic capacitor, and the electrolytic capacitor acts as a buffer. The inductor stores the energy between the two switches. The two switches, the upper switch and the lower switch operate as pulse width modulation (PWM) to produce a high frequency current conduction. The high frequency current passes through the inductor and the output regulation circuitry. The output regulation circuitry is made up of the output control logic and the output voltage feedback device. The output control logic is used to compare the internal reference voltage and the voltage input to the output control circuit to produce a PWM signal. The output voltage feedback device is used to adjust the PWM signal to maintain the desired output voltage. Once the desired output voltage is achieved, it is regulated and output through the output capacitor.

To summarize, NJU7660AM-TE1 is a DC DC switching regulator, belonging to the voltage regulator family of PMIC. It is suitable for a wide range of applications and provides high efficiency, low output ripple, low noise and improved Dynamic response. Its working principle consists of DC/DC power conversion circuit, voltage regulator circuit and two switches in order to deliver the desired output voltage.
