DC-DC converters are an indispensable part of modern electronics technology, providing a range of power conversion services in many different applications. The V375C3V3E50BL is one such device, a specialized module for converting a specified DC voltage input into multiple output voltages. It has been designed as a drop-in solution for a variety of systems requiring precise voltage control and flexible circuit layouts.

The V375C3V3E50BL is a synchronous buck converter operating with a wide-input voltage range and multiple output voltages. It features adjustable output voltages as low as 0.9 V. The device is capable of providing output voltages up to 3.3 V and up to 50 A current output on each output. The voltage regulation of the device is very fast and it can respond to fast load transients with excellent load regulation performance.

The device has been designed for easy integration in a variety of applications. Its wide operating temperature range (up to +125 °C) and small 0.495"×0.687" package size make it suitable for use in space-constrained applications. Its high efficiency, no-load power consumption, and low quiescent current make it an ideal choice for battery-powered applications.

The V375C3V3E50BL usually operates from a single DC input voltage, typically supplied by the main power source for the application. It includes three high-side N-MOSFETs which switch the current from the input to the filter inductors. When the high-side switches are on, current flows from the input supply through the high-side switches to the inductors, and the inductor current increases. When the high-side switches are off, the stored energy in the inductor is released back into the storage capacitors, generating the output voltage.

The microcontroller-based control loop adjusts the duty cycle of the power switching stages. Adjustments can be made to limit the maximum output current or to maintain a specified voltage output accuracy as the load changes. The output voltage can also be regulated by means of current mode or voltage mode control, depending on the application requirements.

The V375C3V3E50BL is suitable for a wide range of applications, including LED driver, medical device, microprocessor power, automotive, industrial, or consumer electronics. It offers a high level of functionality and features, enabling it to power a range of devices with precise voltage regulation and high efficiency.
