DC DC converters are electrical devices used to convert DC voltage or current into a different DC voltage or current to suit electronic equipment. The most common type of DC DC converter is the switching power supply, which uses switches to rapidly switch components within the device on and off to convert voltage or current. The VE-22H-EW-F4 is a high-efficiency isolated DC-DC converter specifically designed for use in optical fiber transceivers.

The VE-22H-EW-F4 is a high-efficiency DC to DC converter with efficiency ratings up to 97%. The converter features wide input voltage range from 3.3V to 21V and output current up to 4A. It is equipped with a built-in active PFC controller and two controlled on/off high-side switches, which reduce switching losses and minimize EMI.

The VE-22H-EW-F4 can be used for a wide variety of applications, including wireless communication, specially designed for A/V products and automotive equipment. The device is also ideal for applications such as networking, control signals and remote sensing. For example, the device could be used to provide a constant voltage or output current for a network switch or router.

The working principle of the VE-22H-EW-F4 is based on the multiplexing feedback control technology. The input is transformed to an approximate sinusoidal waveform to reduce harmonic distortion. The frequency of the sinusoidal waveform is proportional to the input voltage, allowing the device to maintain stable output current over a wide range of input voltages.

The VE-22H-EW-F4 features several protection functions including over-current, over-voltage, under-voltage, over-temperature and Over-power protection. The converter is also equipped with primary and secondary side soft-start feedback loops, which limit inrush current and power surge at the time of startup.

The VE-22H-EW-F4 DC to DC converter is a versatile and efficient device that is ideal for use in a variety of applications including wireless communication, networking, control signals and remote sensing. It features a wide input voltage range and a high efficiency rating, making it an excellent choice for applications where performance and efficiency matters.
