A DC-DC converter is a device that converts DC voltage from one level to another. The V28C24H100BL3 is one of several such converters on the market. It has a wide range of applications and is a popular choice among users needing a programmable, low-power, reliable DC-DC converter. In this article, we\'ll take a look at the application field and working principle of the V28C24H100BL3 DC-DC converter.

The V28C24H100BL3 is a key component in applications such as industrial and automotive voltage regulation, avionics, DC-DC power supplies, and UPS systems. It has a wide input voltage range of up to 48 volts, and can supply up to 24V of regulated output voltage. The high-frequency PWM circuit of the V28C24H100BL3 makes it suitable for high-efficiency applications. Its built-in synchronous rectification feature greatly reduces power losses when compared to traditional linear voltage regulation systems.

In addition, the V28C24H100BL3 features programmable output voltage, over-voltage protection, short circuit protection, remote control, and adjustable switching frequency. This makes it an ideal choice for reliable, accurate, and cost-effective DC-DC conversion. The device can be mounted to a printed circuit board and comes with a two-year warranty for added assurance.

The working principle of the V28C24H100BL3 is based on a current-mode pulse-width modulation (PWM) scheme. The power device of the converter is switched at a high frequency and the output voltage is regulated by varying the duty cycle of the PWM signal. This enables the output voltage to remain unaffected by changes in input line voltage, load current, and temperature.

The V28C24H100BL3 also uses synchronous rectification for enhanced efficiency and reduced power losses. In a typical converter, an inductor stores power during each on-cycle of the PWM switch. When the switch turns off, the stored energy is released as current, resulting in power losses due to the voltage drop across the switch. Synchronous rectification eliminates these losses by using a MOSFET switch in the output circuit to reverse the current flow. When the PWM switch turns off, the MOSFET switch turns on and the stored energy is released as current in the opposite direction, resulting in near-zero power losses.

In conclusion, the V28C24H100BL3 is a powerful and reliable DC-DC converter used in a variety of applications. It features synchronous rectification for enhanced efficiency, built-in protection features, and a wide input voltage range. This makes it an excellent choice for applications that require precise DC-DC conversion. Additionally, its programmable output voltage makes it suitable for a variety of voltage regulation tasks.
