Introduction to NN30195A-VB DC DC Switching Regulator

The NN30195A-VB is a DC/DC switch regulator developed by Nichicon Corporation. It is a packaged, high-efficiency switching power supply featuring a board-mounted device that can be used to convert a variety of input voltages into a 3.3 V, 5 V, or 12 V output. It offers a wide input voltage range of 5.5 V to 36 V and delivers an output current up to 8A (10A peak). The device includes an integrated MOSFET, current-limit protection, soft-start, and over-voltage protection. Additionally, the NN30195A-VB provides excellent transient response, high efficiency, and low noise operation.

Application Areas

Given its wide input voltage range, the NN30195A-VB has various applications. It is ideal for embedded systems, industrial equipment, communication equipment, automotive applications, and other situations requiring a reliable power supply. In industrial applications such as intelligent instruments, sensors, and controllers, it can deliver the precise power required for a wide range of applications. The device also excels in automotive applications, providing a reliable power source for HVAC, infotainment systems, power steering systems, and other automotive components.

Working Principle

The NN30195A-VB DC/DC switch regulator utilizes a synchronous rectification technique that switches a pair of MOSFETs to regulate the output voltage to the desired level. The device operates in three main modes – the PWM mode, the PFM mode, and the PSR mode. In the PWM mode, the regulator will adjust the switching frequency to regulate the output voltage as the load current changes. In the PFM mode, the regulator will reduce the switching frequency when the output voltage approaches its target level, resulting in lower dissipation and improved efficiency. Finally, in the PSR mode, the regulator switches into an extended-duty cycle to maintain the output voltage. In addition to the three operating modes, the NN30195A-VB also has several protection features, such as over-current, over-temperature, and over-voltage protection. The device also features a soft-start function to reduce inrush current. The NN30195A-VB comes in an SIP package and is easy to install and use.

Conclusion

The NN30195A-VB DC/DC switch regulator provides efficient, reliable power conversion in a wide range of application areas. Its wide operating temperature range and extensive protection features make it suitable for high-reliability applications in a variety of environments. The NN30195A-VB is an ideal solution for applications requiring reliable, clean power with excellent transient response.
