DC DC converters are electronic devices used to convert a direct current (DC) into a higher or lower voltage feed. The NVD0.3EHH-M6 DC/DC converter is a compact, cost-effective solution for applications such as communication, industrial, instrumentation, and medical. It comes in a variety of package sizes and offers a wide range of input and output voltages with low-noise, high power density, and high efficiency.

The NVD0.3EHH-M6 is packed with features to satisfy the most demanding applications, including a high peak current of 300A, wide input and output voltage range (2.4V-3.6V and 5V-15V respectively), and an isolated power design with high-efficiency, low standby power consumption and wide temperature range.

It is rated for user-adjustable output voltage between 5V and 15V at up to 150mA of output current, along with a wide input voltage range of 4.5V to 14V and can operate up to 100C in case temperature. Output ripple is as low as 28mVpp, with output-to-input isolation of 2.5KVac. Its efficiency can reach up to 92%, and the power density can reach up to 25W/in³, making it suitable for use in small, space-constrained applications.

The working principle of the NVD0.3EHH-M6 is based on a buck-boost topology. An external control winding is added to the traditional buck-boost circuit. The external winding is used to adjust the output voltage by controlling the peak current in the switching transistor, thereby eliminating the pulses on the inductor current. Unlike traditional buck-boost converters, this circuit is able to constant current mode. This eliminates the need of an external component, such as an inductor or a capacitor, to regulate the operating frequency. Moreover, it’s low ripple and over/undervoltage protection make it highly reliable.

In summary, the NVD0.3EHH-M6 is a cost-effective, high power density, isolated DC DC converter that offers a wide input and output voltage range with low-noise, high efficiency and a wide temperature range. It can be used in a variety of applications such as telecommunications, industrial, instrumentation, and medical.Its buck-boost topology allows for constant current mode, making it an ideal solution for a variety of demanding applications.
