DC-DC converters are voltage regulation devices designed to convert one DC voltage level to another. They are essential components in modern electronic systems that run on different supply voltages. V375A28H400BS is a step-down DC-DC converter with a maximum output voltage of 28V and a maximum output current of 400mA. With its wide input range of 4.5V to 28V, it is suitable for a variety of applications in industrial, commercial, and consumer applications.

V375A28H400BS is a non-isolated, synchronous switching step-down converter based on inductor-capacitor (LC) filter. It uses an external inductor and capacitor, together with a MOSFET to lower input voltage to a desired output level. The converter is built on the basis of a fixed switching frequency, which enables it to achieve a high efficiency - typically up to 93%. The high efficiency eliminates the need for a heatsink.

As the operating temperature varies, this DC-DC converter has an integrated thermal protection circuit to protect it from overheating. The protection circuit will shut down the converter when the temperature exceeds a certain threshold, and then automatically recover when the temperature returns to the safe range. The user can also select the temperature protection threshold via an external resistor, making it easy to fine-tune the system.

V375A28H400BS is an ideal component to use in battery operated devices. With its low quiescent current of only 13μA, it helps extend the battery life significantly. Apart from this, the converters also feature cycle-by-cycle current limit protection and short-circuit protection, making them suitable for use in high-reliability applications.

This DC-DC converter has a wide range of application possibilities. It can be used in smart watches, industrial automation, medical equipment, automotive, telecommunications, and other various consumer electronics. By combining the compact size of the package and a wide operating temperature range of -40 to +125 Degrees Celsius, it is suitable for high-density space-constrained applications like hand-held electronic gadgets and small appliances.

V375A28H400BS is an advanced step-down DC-DC converter that offers a lot of flexibility and efficiency. With its wide input range, low quiescent current, thermal protection, current limit protection, and short-circuit protection, it is a great choice for a variety of applications.
