DC DC Converters

The VE-270-IY-F2 DC to DC Converter is a high-efficiency switching regulator that converts an input DC voltage to a regulated output DC voltage. The converter includes a digital controller, a voltage regulator with a low on-resistance output switch, and high current output filter elements. The input voltage is adjustable from 3.3V up to 28V, and the output voltage is adjustable from 0.8V up to 5V with a maximum output current of 10A.

Features

The VE-270-IY-F2 DC to DC Converter features an adjustable-frequency, constant-output switching regulator, and advanced power-management capabilities. The voltage and current loop circuits of the converter provide accurate voltage and current control, even with high-current loads and fast-changing input voltages. The converter also includes protection features such as overvoltage, undervoltage, overload, and short-circuit protection.

Generic Topology

The VE-270-IY-F2 DC to DC converter is one of the most widely used generic converters. It features a fully-integrated high-frequency switching regulator with an adjustable-frequency circuit, a regulation loop, and a filter network. In the generic topology, the AC power source is converted to a DC voltage which is applied to a step-up or buck-boost transformer. The transformer converts the AC input voltage to a high-frequency output voltage which is applied to the output filter network. The filter network smooths out the waveform, and the DC output voltage is generated from the filtered voltage.

Application Fields

The VE-270-IY-F2 DC to DC converter is suitable for a variety of applications, including industrial automation, renewable energy, telecom, automotive, military, and medical. It is particularly suitable for applications where fast response and high efficiency are required. It is also well-suited for battery-powered applications, where the converter has the ability to maintain a steady output voltage over the entire battery discharge life. The converter can also be used in high-temperature applications, since it is capable of operating at temperatures up to 100°C.

Working Principle

The VE-270-IY-F2 DC to DC converter works on the principle of voltage regulation. The converter features a digital controller that monitors the input voltage and adjusts the output voltage to achieve the desired output voltage. The controller is capable of adjusting the output voltage from 0.8V up to 5V with high-speed switching pulses. The output current is controlled by adjusting the duty cycle of the pulses. The output voltage is maintained constant by the voltage regulation loop, which compares the output voltage to a reference voltage and adjusts the duty cycle of the pulse as necessary. The output filter elements further smooth out the waveform of the output voltage, which results in a steady output voltage and low electrical noise.
