NN30295A-VB Application Field and Working Principle

PMIC - Voltage Regulators - DC DC Switching Regulators

NN30295A-VB is an integrated power solution IC from ROHM Semiconductor. It is a DC-DC switching regulator that combines an integrated boost controller and an integrated low dropout regulator. It is specifically designed for low power applications such as digital forensics. It can be used for automotive electronics and point-of-load applications.

This integrated power solution IC can be used to regulate input voltages ranging from 4.0V to 14V. It is designed to operate with a maximum output current of 2A. It has a built-in MOSFET, which allows the output voltage range to be set from 0.8V to 5.5V. It has a wide range of features such as protection functions, soft-start, and adjustable regulation.

In terms of application field, NN30295A-VB can be used in automotive electronics, battery operated applications, and medical equipment, among others. It can also be used in point-of-load applications where high efficiency, low quiescent current, and wide input voltage range are required. It is a very popular choice for digital forensics as it has built-in safeguards against reverse polarity and input surge protection.

This IC operates in one of two main modes: switching mode operation and linear mode operation. In switching mode operation, it utilizes high-speed power MOSFETs in its integrated boost controller section. The switching frequency can be set to as high as 1MHz. The operational frequency can be set to about 0.3MHz for a lower noise operation. In linear mode operation, the output voltage is regulated using a low dropout regulator that utilizes an NMOS in its circuit design.

The protection functions of this IC include over-current protection and over-temperature protection. It is also equipped with a soft-start circuit to prevent high inrush current at start-up, and can be preset to a specific output voltage range. The integrated power solution IC also has a gate driver for control of the power MOSFET.

In summary, NN30295A-VB is an integrated power solution IC from ROHM Semiconductor that is specifically designed for low power applications such as digital forensics. It has a wide range of features and is suitable for point-of-load applications where high efficiency, low quiescent current, and wide input voltage range is desired. It operates in two main modes: switching mode and linear mode, and has protection functions such as over-current protection and over-temperature protection.
