The ADVFC32SH is a highly efficient and reliable V/F and F/V converter. Its applications range from ac-dc power supplies, dc-dc converters, and multiple output supplies, such as LED driver, dc-dc step-up and step-down converters. This product offers an impressive range of features including adjustable output voltage and frequency, as well as accurate and stable current and soft start functions.

The ADVFC32SH operates through the application of two distinct switching techniques. Firstly, a synchronous rectifying technique is used in order to provide high efficiency, low power consumption, improved power density and lower noise than conventional rectifying techniques. Secondly, Active Frequency Tracking (AFT) technology is employed to ensure that the declared voltage and frequency remain stable, even when changes to the load or power supply occur.

The ADVFC32SH also has many additional functions built-in which provide further flexibility and protection for the user. First, multiple protection functions are available including under voltage lockout, over voltage lockout, primary side over temperature protection, and primary side current limit. Also, the device provides good EMI noise mitigation and HF Ripple curb, with selectable switching frequency. Furthermore, there are several soft start options available with no external components required.

The ADVFC32SH includes an internal reference voltage for the voltage regulator, allowing the output voltage to be set accurately. This is achieved by utilizing a novel linear regulator technique to convert the PWM waveform into a low impedance voltage waveform. Additionally, the DC/DC converter has an adjustable frequency operation, which is driven by an internal oscillator. This can be used to precisely control the switching frequency, to optimize performance and minimize EMI noise.

The ADVFC32SH can support a wide range of output power levels, with multiple input and output voltage and current levels supported. This, combined with its elegant and robust design, makes it suitable for a broad range of applications in the industrial, consumer, and automotive markets. Further, the ADVFC32SH is able to provide optimum performance in conjunction with several different operating topologies, including Boost, Flyback, Push-Pull, and Half-Brick.

Overall, the ADVFC32SH is an excellent choice for a wide range of applications requiring reliable and efficient conversion of voltage and frequency. It features a number of features to provide superior performance and protection, while also being user-friendly and providing flexible options. The accuracy, stability, and many other features make the ADVFC32SH an exemplary choice in Voltage/Frequency and Frequency/Voltage converters.
