DC-DC converters are units that convert a direct current (DC) source of one voltage to another voltage. A DC-DC converter ideal for many electronic designs, such as laptop and portable devices, is the VE-B3R-IW-F4. This DC-DC converter features a very wide input voltage range of 4.5 to 60 V, an adjustable output voltage, and high efficiency of more than 93%.

VE-B3R-IW-F4 Application Field

The VE-B3R-IW-F4 is capable of supplying 4.5 to 60 V input voltage and delivers output voltage up to 15 V. This converter is an ideal solution for portable systems using alkaline, NiMH, NiCd, LiFePo4, or lithium-ion batteries with a wide range of input voltages. Additionally, this unit is also ideal for general purpose AC/DC and DC/DC applications that require a wide operating temperature range and good efficiency. The inherent flexibility of this converter allows operation in a wide range of environments. Finally, the converter has built-in EMI filtering and protection, providing safe operation in a noisy EMI environment.

Working Principle

The VE-B3R-IW-F4 is a DC-DC buck (step-down) converter module. It works by converting the input voltage to a substantially lower output voltage. This is accomplished via the use of an inductor, a switch, a power transistor, and a control circuit. The inductor is connected in series with the switch and power transistor, and when current passes through the circuit, a magnetic field is created by the inductor. When the switch is turned on and off, the magnetic field in the inductor collapses and expands, inducing a voltage spike that is stepped down according to the inductor\'s value. This voltage is then further conditioned and regulated to create the desired output voltage.

The control circuit of the VE-B3R-IW-F4 converts the input voltage into a pulse width modulated (PWM) signal. This PWM signal is then used to control the power transistor, which turns the input voltage on and off according to the PWM signal. This is what allows the device to convert the voltage from the input to the output. The PWM control also allows the converter to maintain a constant output voltage despite changes in the input voltage.

Conclusion

The VE-B3R-IW-F4 is a versatile DC-DC buck (step-down) converter module that offers a wide input voltage range, adjustable output voltage, and high efficiency. This unit is an excellent choice for portable devices, general purpose AC/DC and DC/DC applications, and environments with noisy EMI. Thanks to its built-in EMI filtering and protection, the converter can be safely operated in a variety of EMI-prone environments. By converting the input voltage to a substantially lower output voltage, this converter provides a reliable and cost-effective power solution.
