P35-12-FST

AC DC Converters

AC/DC converters are used to convert AC (alternating current) power into DC (direct current) power. This is an efficient way to power different types of electronic devices or systems that require a steady current input to operate. Generally speaking, AC/DC converters are widely used in home appliances and other industrial applications. The most commonly used AC/DC converters today are called Pulse Width Modulation (PWM) or Pulse Frequency Modulation (PFM) converters.

P35-12-FST Application Field and Working Principle

The P35-12-FST is a 12V/3A, 125 kHz Resonant Boost Converter, designed for input voltages ranging from 0.75V to 6V. It can be used as a source of power for portable electronic devices or LED lighting. This converter utilizes the resonant technique which allows the converter to work at a very high efficiency over a wide range of input-output voltages and frequencies. The main principle of operation is to convert AC power to DC by modulating its frequency. This is done by creating a sinusoidal voltage waveform that is then converted to a square waveform with pulses of varying width.

The P35-12-FST is designed to provide a high efficiency AC/DC converter by utilizing two main components, the MOSFET transistor and the resonant tank circuit. The MOSFET transistor acts as a switch that switches the voltage on and off at different frequencies to achieve an AC output. The resonant tank circuit is used to keep the frequency of the AC waveform consistent over a wide range of input-output voltages and frequencies. This helps to ensure a high efficiency conversion.

In addition to its high efficiency, the P35-12-FST also offers some additional features that make it an attractive choice for portable electronic devices and LED lighting applications. For example, it includes under voltage protection and temperature protection circuitry to protect against short circuits or overloading. Additionally, the converter includes a power-on reset functionality which will turn the device on automatically if the input voltage is restored after a power outage. This is especially useful for devices that may need to be kept in a standby state when the power is out.

Overall, the P35-12-FST is a great choice for those looking for an efficient AC/DC converter. Its wide range of input-output voltages and frequencies help to ensure a high conversion efficiency, and its additional features make it a great choice for portable electronic devices and LED lighting applications.
