NN30320A-VB Application Field and Working Principle

DC DC Switching Regulators

NN30320A-VB is a widely used DC DC switching regulator. It is an efficient three terminal regulator, featuring an adjustable voltage output from 0.8V up to 7.2V. It is designed for use as a main system power supply or for supplying power for smaller peripherals. It is commonly used in automotive, railway, telecom, and computer industries, as well as other applications.

In DC DC switching regulators, an input voltage is applied to two switching transistors in an ON-OFF sequence. These two transistors control the input current, thus regulating the output voltage. Voltage feedback is then fed back to a sense voltage comparator. This detects the output voltage, triggering the loading transistors accordingly.

NN30320A-VB has excellent regulation characteristics, which can provide a stabilizing voltage output with minimal ripple even with changes in loading or environmental conditions. The device is built-in with protection over current protection (OPC) to prevent it from overloading and over-temperature protection (OTP) to prevent possible damage due to overheating. It also supports pre-ramp and smooth start-up, soft shutdown, and auto-standby.

The device is designed as a three-terminal regulator, with input and output terminals connected to the common ground. Together with its excellent stability and overload protection features, it is ideal for applications requiring high current driving with low noise and low voltage drop.

The NN30320A-VB is able to operate reliably in temperatures ranging from -42°C to +125°C. Furthermore, its adjustable output voltage from 0.8V up to 7.2V makes it suitable for a wide range of applications. Its high feature set and long life span make it an ideal solution for a variety of systems.
