DC DC converters make it possible to efficiently power digital devices with a clean DC voltage. The V72C15C150BS3 is one such converter, designed with the efficiency and flexibility required for modern and future digital applications. This article will cover the application field and working principle of the V72C15C150BS3 DC-DC converter.

The V72C15C150BS3 is a non-isolated, dual phase synchronous buck converter. It uses pulse width modulation (PWM) to accurately control the voltage output of the device. It supports output voltages between 1.2-4.5V, a maximum output current of 15A, and a peak power of 140 watts. It includes both current mode and voltage mode control for improved power conversion efficiency, and can convert an input voltage between 3-14V.

The V72C15C150BS3 is designed for use in high power industrial applications, such as industrial automation, transportation, power supplies, LED lighting, and medical equipment. It is ideal for applications that require accurate voltage control and high efficiency. It is highly efficient, with a maximum efficiency of up to 95%, and can also operate with low output current, as low as 10 mA.

The working principle of the V72C15C150BS3 is based on PWM control of the duty cycle of the output voltage. The device uses two synchronizing signal pairs, one for voltage and one for current, to detect pulses and adjust the output voltage. The current mode control utilises external high-side and low-side N-MOSFETs that are triggered on each falling edge of the voltage sensing signal. During the high side switch cycle, the high side switch is opened upon receiving the voltage sensing signal and the low side switch is closed, and vice versa during the low side switch cycle. This action creates an output voltage across the inductor that is equal to the difference in input and output voltages. The current mode control is then used to adjust the duty cycle of the switches to maintain and regulate a constant voltage output.

The V72C15C150BS3 DC-DC converter is a high-performance, efficient converter suitable for industrial applications requiring a stable, low-noise power supply. Its versatility, high efficiency and low output current make it useful for a range of digital applications, from medical equipment to LED lighting. The device is capable of accurately controlling the output voltage of the device using PWM and current mode control.
