The NN30312A-VB is a DC to DC switch regulator designed for precision step-down DC to DC conversion. It features a wide input voltage range, adjustable output voltage and is designed for low noise and high efficiency applications. It can be used for powering, lighting and other purposes in systems and products with different input power requirements.

The NN30312A-VB is an adjustable step-down DC to DC switch regulator, capable of outputting up to 2A of load current to power micro-controllers, processors, displays and other application loads requiring low voltage and current regulation. It allows the user to precisely adjust the output voltage within a range of 5V to 24V. The device includes both Class I (no standby current) and Class II (standby current) power options. Its cycle-by-cycle current limit protection and over-temperature protection make it ideal for high efficiency and robust performance applications.

The NN30312A-VB features low-power input voltage coding and true-load disconnect for light-load applications. It operates over a wide temperature range and offers high efficiency over a wide load range. In addition, it offers output voltage accuracy of ±3%, fast transient response, low noise operation and excellent line and load regulation.

The NN30312A-VB’s working principle relies on the PWM switching mode of operation. It uses a closed loop current mode control with a wide feedback voltage range for excellent line and load regulation. It features a constant switching frequency with low-ripple current switching and low-noise output. In addition, it includes built-in soft-start to provide smooth power up and current limit protection. This feature allows the device to remain protected during overload conditions while limiting the current used to protect the load.

The NN30312A-VB is well-suited for a wide variety of applications, which include battery-powered systems, power supplies, telecom and datacom systems, industrial control, and distributive power systems. The NN30312A-VB is an ideal DC to DC converter for precision power applications due to its wide input voltage range, adjustable output voltage, and high efficiency.
