VI-J72-CX-F2

DC DC Converters

DC DC converters are electronic circuits that are designed to step up or step down voltage levels in order to match the electrical requirements of particular equipment. A DC DC converter typically consists of a high-frequency transformer with an additional winding, along with a set of semiconductor components, such as a rectifier diode and field effect transistors (FETs).

The VI-J72-CX-F2 DC DC converter is a surface mountable, high-efficiency boost step up DC DC converter which can be used to convert input voltage of 3.3V to 5V, 5V to 12V, 12V to 15V, 15V to 24V, etc. It features excellent transient response and low ripple. The device is presented in a SOT26 package.

Application Field

VI-J72-CX-F2 converters are commonly used in a variety of applications situated in portable consumer electronic devices, such as mobile phones, personal digital assistants (PDA\'s), digital cameras, and game consoles. It can also be found in telecom, test equipment, wireless networks, and instrumentation.

Working Principle

The VI-J72-CX-F2 operates on the principle of high-frequency pulse width modulation (PWM). According to this technique, the output voltage is regulated by varying the duty ratio of voltage pulses. The high frequency operation of the converter ensures that the output ripple voltage is very low.

The VI-J72-CX-F2 converter has an inherent overvoltage protection circuit, which turns off the output switch when the output voltage exceeds a certain limit, thereby avoiding short circuits or high voltages. The device also offers an adjustable output voltage, where the output voltage can be adjusted by the way of connecting an external resistor.

The VI-J72-CX-F2 DC DC converter has high power density, low start-up current, and low EMI noise, all of which makes it a very efficient and reliable device for a range of applications.
