DC-DC converters are devices that convert direct current (DC) electricity from one voltage level to another. The V300B15T250BS is a medium power DC-DC converter designed to convert input voltages from 36V to 75V DC to a single output voltage of 15V DC, 250W. This device is suitable for a variety of applications where better power density and higher efficiency are desired.

The V300B15T250BS features an active function and is based on a synchronous rectification topology. It has a high efficiency of up to 96% and a wide input voltage range; both of which contribute to its improved power density. In addition, the device also provides enhanced inrush current limiting and power cycling protection.

The V300B15T250BS has several applications and can be used in a wide range of applications where input voltage is from 36V to 75V DC and output voltage needs to be precisely regulated to 15V DC. Examples of such applications include battery-powered industrial equipment, telecommunications, and portable medical systems.

The working principle of the V300B15T250BS is based on the synchronous rectification converter topology. It has two distinct circuit sections. The first section is the DC-DC converter, which converts the input voltage from 36V to 75V DC to an intermediate voltage that is then used by the second circuit section, the controller, to generate the regulated output voltage of 15V DC.

The controller circuit consists of an integrated high-frequency switching frequency of up to 400kHz, a voltage regulation system, and an overload protection circuit. The high-frequency switching causes inductor current pulses, while the voltage regulation system ensures a stable output voltage. The overload protection circuit consists of a foldback and power-cycling function, providing a safe, reliable operation.

The V300B15T250BS is a medium power DC-DC converter that provides a high efficiency rate of up to 96% with a wide input voltage range of 36V to 75V DC. This device is suitable for applications such as battery-powered industrial equipment, telecommunications, and portable medical systems where input voltage is from 36V to 75V DC and output voltage needs to be precisely regulated to 15V DC. Its working principle is based on the synchronous rectification converter topology with two circuit sections: the DC-DC converter and the controller. The device also has power-cycling and overload protection capabilities, providing a safe and reliable operation.
