NPH25S2403EIC

DC-DC Converters

DC-DC converters are devices that convert a DC input voltage into a different DC output voltage. The NPH25S2403EIC (EIC) is a SIP package DC-DC converter designed for use in industrial systems or other applications requiring low-power switching. The EIC is a full-bridge DC-DC converter with synchronous rectification, using two N-channel MOSFETs as the input, and two Schottky rectifier diodes at the output.

Application Field and Working Principle

The NPH25S2403EIC has a wide range of applications in the industrial field. It can be used as an isolated DC-DC converter in applications requiring a regulated output voltage, such as power supplies, motor controls, and regulators. It can also be used for automotive applications such as lighting and HVAC systems. Additionally, the EIC can be used as a step-down regulator for both AC and DC motors.

The basic working principle of the NPH25S2403EIC is based on the synchronous rectification of two MOSFETs, one N-channel and one P-channel MOSFETs. The two MOSFETs are switched ON and OFF at different timing sequences to convert the DC voltage into the desired regulated DC output voltage. The output voltage can be further adjusted by adjusting the duty cycle of the MOSFETs. The EIC also has a wide input-voltage range, and can accept a voltage input range of 4V to 28V.

The NPH25S2403EIC provides good thermal performance and reliable operation in harsh temperature environments. It is also very robust and has a wide output current range. The converter has a low quiescent current and low-noise operation for improved efficiency. The EIC is also protected against over-temperature and over-current conditions, and also has an on/off control feature.

The NPH25S2403EIC is a full-bridge DC-DC converter with synchronous rectification, providing an efficient, reliable and cost-effective solution for a variety of industrial applications. Its wide input voltage range and low-noise operation make it suitable for applications such as power supply regulation, motor control, lighting and HVAC systems, as well as for step-down regulators for AC and DC motors.
