DC-DC converters have become an essential component in practically all electronic and electrical systems applications. To manage power in an efficient way requires roughly two types of power conversion units - AC to DC converters and DC to DC converters. AC to DC converters are used to provide a steady DC output voltage from a fluctuating AC mains input voltage. DC to DC converters are designed to convert different DC input voltages into specific and desired DC output voltage values. One type of DC to DC converter is VE-B1Y-EY-S converter.

VE-B1Y-EY-S is a non-isolated DC-DC step down voltage converter module. It can step down lengthy input voltages into many output voltage levels, suitable for different types of electronic and electrical apparatus. VE-B1Y-EY-S can to turn the input voltage of 9V-48V to 3.3V/5V stable output voltage. It has high efficiency, low voltage ripple and inevitable overload-short circuit protection, making it an ideal choice for use in automotive, industrial, LED display, LED lighting, electric tools, other electro-electronic or electrical application.

The working principle of VE-B1Y-EY-S converter is simple. It starts with a wide input voltage range. The central part of this design is an integrated circuit (IC) incorporating a PWM controller, a switch designed for automobile applications and active components along with some passive components. These active and passive components together are utilized to reduce the supply voltage. This DC-DC converter has an integrated switch controller and power FET, with some drive control and protection circuits. When a voltage is applied, the switch is turned on and off at a certain percentage of time due to the control of the PWM controller. As a result, the average current passing through the switch is measured and the output voltage is calculated accordingly, with the help of the current sense resistor and detected by the feedback pin. Thus, this type of switching converter can easily and efficiently convert input DC voltage to the desired output voltage.

VE-B1Y-EY-S converter is not only applicable to industries such as electric vehicle, utilities and power generators, but also for other automobile applications, LED display, LED lighting and electric tools, etc. It has advantages of reducing input voltage ripple, stable output current, lower standby power loss and high energy efficiency. Besides, this converter is relatively efficient compared to the standard linear regulator making it more cost-effective. With the increasing demands of applications requiring the conversion from one voltage level (e.g. 48V) to another (e.g. 12V), VE-B1Y-EY-S converter has become a good choice in many of these applications.
