DC DC Converters

DC-DC converters are electronic devices that are used to change DC voltage in a circuit from one level to another. They are commonly used to adjust voltage levels in a wide range of applications, and are an essential part of almost all modern power systems. One such type of DC-DC converter is the VI-22N-CX-B1, which features a high-efficiency synchronous buck-boost converter design.

The VI-22N-CX-B1 converter is especially useful for applications that require a wide input voltage range, such as portable and automotive power systems. It features a wide input voltage range of 4V to 22V and a 3.3V regulated output voltage. It also offers a low-power shutdown mode that minimizes power consumption during periods of inactivity. The converter also features a programmable soft-start, and a dedicated 3-pin enable pin to reduce power-up time.

The primary function of the VI-22N-CX-B1 is to convert a wide input voltage range to a 3.3V regulated output voltage. This is accomplished by a synchronous buck-boost converter topology. This type of converter design uses an inductor and two switching transistors to store energy and regulate output voltage. The two switching transistors are controlled by a pulse-width modulator (PWM) circuit, which regulates the voltage by varying the duty cycle of the transistors.

The VI-22N-CX-B1 offers a high efficiency of up to 90%, which minimizes power loss and increases system reliability. The converter also features a high operating frequency of up to 2.4Mhz, making it suitable for high-speed applications. Additionally, the converter offers a wide selection of protections such as over-voltage protection, under-voltage lockout, and over-temperature protection.

The VI-22N-CX-B1 provides a reliable and efficient way to regulate voltage in a wide range of applications, from portable and automotive power systems to industrial and medical applications. With its wide input voltage range, high efficiency, and integral protection features, the converter is the perfect choice for applications that require a high level of performance and reliability.
