DC-DC converters provide a wide variety of power conversion possibilities in the form of AC to DC, DC to DC, stepper motor, and transformers, among many other applications. One such converter is the VE-20H-IY-S. This converter is particularly suitable for applications that require a relatively low-cost, robust, and reliable power conversion solution.

The VE-20H-IY-S is a synchronous buck converter with an input voltage of 20 VDC. It is designed to provide an output voltage of either 5 or 12 VDC, depending on the application, and has an adjustable output current of ≤2 A. The converter also has an internal temperature-monitoring circuit with a shut-down temperature of 130°C ± 10°C , which protects the device from potential damage due to overheating.

The VE-20H-IY-S uses synchronous rectification technology, which is the process of converting AC power into DC power. This is achieved through the use of two MOSFETs (Metal Oxide Semiconductor Field Effect Transistors), with one MOSFET switching on during the positive cycle of the AC input voltage and the other MOSFET switching on during the negative cycle. This allows the two MOSFETs to act as the switches of a rectifier circuit, allowing the slow AC voltage signal to be quickly converted into a DC voltage output.

In addition, the VE-20H-IY-S uses pulse-width modulation (PWM) to regulate the output voltage and current. PWM is a control technique used in switching power converters, which allows for the output power to be regulated by varying the width of the pulses of the input AC signal. This is done by varying the ratio of on and off times of the two MOSFETs in the synchronous rectifier circuit. The ratio of on and off times determines the amount of power output, and this can be adjusted to achieve the desired output voltage and current.

The VE-20H-IY-S is a low-cost, efficient, and reliable DC-DC converter, suitable for a wide variety of applications. Its adjustable output current, temperature monitoring circuit, and synchronous rectification technology make it an attractive choice for use in multiple applications, such as voltage regulators, battery chargers, and power supplies.
