DC-DC converters are used to convert one DC voltage to another using electronic switching devices. V375B28C300BN2 is a DC-DC converter module designed by VACUUMSG. It is a highly efficient, low cost, low noise and low profile device.V375B28C300BN2 utilizes a synchronous rectification voltage regulator topology to convert a DC voltage from an input source to a regulated DC voltage at the output. The module features a wide 4.5-20V input voltage range and a regulated 8.3-21.4V output voltage range. It has a high efficiency of up to 98.5% and a maximum output current of 300mA. The module also features built-in overcurrent, overvoltage and overtemperature protection, as well as thermal shutdown.V375B28C300BN2 is suitable for a wide range of applications including mobile phones, tablets, communications and networking applications, consumer electronics, automotive infotainment systems, industrial systems, power supplies, and heavy-duty equipment.In terms of working principle, the block diagram of the V375B28C300BN2 is shown below. The input voltage is regulated to 8.3V-21.4V by the internal synchronous rectification voltage regulator. The input voltage is converted into a pulsed signal, which is then applied to the synchronous rectifier module. The synchronous rectification reduces the power loss associated with the rectification process. The output voltage is regulated by a sensistor on the primary side of the MOSFET, which regulates the power output and keeps the output voltage constant over a wide range of loads.The first step in the working cycle is the input DC voltage being applied to the primary side of the MOSFET. This voltage is regulated by the sensistor and passes through the MOSFET, causing the current to flow through the winding of the transformer. This current then induces a voltage on the secondary side of the transformer. This voltage is applied to the synchronous rectifier module, which rectifies the signal and provides the required output voltage for the application. This output voltage is then regulated and maintained by the sensitor.The V375B28C300BN2 is a highly efficient, low noise, low cost and low profile DC-DC converter module. It has a wide input voltage range of 4.5V–20V and offers high efficiency of up to 98.5%, with a maximum output current of 300mA. With advanced protection features such as overcurrent, overvoltage, overtemperature and thermal shutdown, it is suitable for a wide range of applications, including mobile phones, tablets, communications and networking, consumer electronics, automotive infotainment systems, industrial systems, power supplies and heavy-duty equipment.
