DC-DC Converters

DC-DC converters are a class of power supply technology used to convert dc power from one voltage level to another, and are typically the most efficient approach to power regulation from one voltage level to another. The V375A5C400BL is a high efficiency, low profile powered supply/buck converter with a maximum output current of 0.6A (600mA) and a 6-pin surface mount package. It is designed for application in the telecommunications, networking, automotive, industrial, and consumer markets.

DC-DC converters are commonly used in a variety of applications, including solar panel/ battery-powered applications, portable devices, and powering microcontrollers or other circuit boards from a single dc source. The V375A5C400BL can be used for a number of different applications, including supplying power to LEDs, providing power to small and medium size digital microcontroller modules, as well as powering PoE applications.

The V375A5C400BL is an efficient DC-DC buck converter that can efficiently step down regulated, variable, or battery input voltages into output voltages as low as 0.6V and as high as 3.75V. It employs peak current mode control technology for fast transient response and excellent stability, and integrated low resistance FETs for low external component count and low noise operation. The converter also features power saving features such as an active bypass feature and programmable soft-start/stop.

The V375A5C400BL’s operating principle is based on an open-loop control method that utilizes an internal oscillator to control the current in the output, referred to as peak current mode control. This control scheme ensures high efficiency, fast response time, and excellent stability for the converter. When the output load experiences varying current demand, the converter can track the load by adjusting the peak current of the output. The converter also has an active current limit to ensure maximum system reliability and isolation between the input and output.

In addition, the V375A5C400BL provides additional features for improved convenience. The soft-start feature gradually increases the output voltage from ground to its programmed level over a selectable duration, reducing the inrush current when powering up the converter. Additionally, the soft-stop feature allows the unit to smoothly decrease the output voltage to ground. This lets designers program the V375A5C400BL to ramp up or down its output current based on the level of power required by the system.

The V375A5C400BL is an efficient, low profile, and precise DC-DC buck converter with a maximum output current of 0.6A (600mA). It is ideal for applications requiring a wide input voltage range, adjustable output voltage, and fast transient response. It can be used in a variety of applications, including supplying power to LEDs, powering digital microcontroller modules, and PoE applications. Its peak current mode control and low resistance FETs make it energy-efficient, while providing fast transient response and excellent stability.
