NJU7660D Application Field and Working Principle

NJU7660D is an intelligent buck converter produced by New Japan Radio Co., Ltd. It is a DC/DC switching converter that is part of the PMIC (Power Management IC) voltage regulator family. With the correct circuit design and application, this device can meet the various power requirements of various electronic devices, such as smartphone, industrial equipment, and digital home appliances.

NJU7660D is a high frequency synchronous buck converter that utilizes the PFM (Pulse Frequency Modulation) control method to sense and control the output voltage. This power module has two independent stages, the power stage and the control stage. The power stage is a powermetal transistor that is used to switch the voltage, and the control stage is used to control the frequency of the voltage switch. This allows for a more efficient and stable output voltage.

The overall working principle of NJU7660D is based on the PFM control of the switching frequency. First, an internal voltage reference circuit sets the desired output voltage and an adjustable voltage divider is used to measure the output voltage. The comparator compares the two voltages and the output of the comparator sets the digital pulse width when turned into pulse width modulation signals. The feedback generates a switching frequency that can be matched to the load and keeps the output voltage constant.

Furthermore, NJU7660D has a variety of features that make it suitable for many applications. Firstly, the low noise and low ripple of the output voltage make it ideal for applications that need to maintain the accuracy of the voltage output. Moreover, the low operating current of the device ensures long standby time with minimal energy consumption. Additionally, the device can support input voltages up to 20V, so it can provide a wide range of applications. These features make NJU7660D one of the best choices for modern electronic device power systems.

NJU7660D is suitable for many applications, such as powering mobile devices, industrial systems and LED lighting. Mobile devices often require accurate and efficient power supply to the CPU, display and other peripherals, and the fast response of the NJU7660D is ideal for this purpose. In industrial systems, the power stage of the device is able to provide a stable, reliable and adjustable output voltage for the system, making it ideal for this application. Finally, NJU7660D also has excellent dimming performance and current limit protection, making it a good choice for LED lighting.

In conclusion, NJU7660D is a DC/DC switching converter that is part of the PMIC voltage regulator family. It utilizes the PFM control method to sense and control the output voltage, and the low noise and low ripple of its output voltage make it suitable for a variety of applications. Additionally, its low operating current and wide input voltage range ensure it can meet the various power requirements of various electronic devices. Therefore, NJU7660D is one of the best choices for modern electronic device power systems.
