PMIC – AC DC Converters, Offline Switchers includes many power solutions for various applications, such as FSQ100. The FSQ100 is one of the best solutions for ac-dc conversion for offline switching applications. With its high power efficiency, adjustable output voltage and accurate temperature control characteristics, the FSQ100 provides an ideal solution for ac-dc power supplies.

The FSQ100 AC-DC Conversion application field and working principle has some basics you need to understand when developing solutions to power the system. The FSQ100 is specifically designed for ac-dc conversion applications which convert the low AC voltage, usually generated by a primary winding in a transformer or a power line, into a higher DC voltage to power the load.

The FSQ100 is an ac-dc buck power supply, which provides an output voltage that is adjustable from 0V to 12.5V. The output voltage is determined by the feedback voltage, which is drawn from the output side of the power supply through a small resistor. The feedback voltage is compared to the reference voltage and the difference is used to control the switching elements in the power supply, which in turn regulate the output voltage.

The FSQ100 contains a high performance switching element, which consists of metal-oxide-semiconductor field-effect transistor (MOSFET). The switching element forms a half-bridge driver that generates a pulse width modulation (PWM) signal. The primary side of the transformer has two different inputs, the primary AC voltage and the PWM signal.

The time-averaged value of the voltage applied to the primary winding of the transformer will be determined by the duty cycle of the PWM pulse. So when the duty cycle is set to a low value, the output voltage is minimized, but as the duty cycle is increased, the output voltage rises and the power is transferred to the secondary side of the transformer. This way, the FSQ100 is able to efficiently convert AC voltage to DC voltage.

The switching frequency of the FSQ100 is constant, it cannot be changed. However, each output is provided with a frequency detection circuit, which is able to detect the switching frequency. So, the switching frequency can be adjusted by changing the output frequency of the transformer. For example, if the output voltage needs to be regulated, the switching frequency can be changed so that the output voltage remains constant.

The FSQ100 also has an accurate temperature control characteristic, which enables the device to maintain an optimal operating temperature. The temperature control is achieved by controlling the switching frequency, so that the power dissipation is kept within the specified limits. This way, the device can operate reliably at higher temperatures.

The FSQ100 also provides an adjustable over-voltage protection and over-temperature protection. The over-voltage protection will turn off the power supply if the output voltage exceeds the set limit. The over-temperature protection will turn off the power supply when the device temperature reaches a certain limit.

The FSQ100 also has an output current and power protection. If the output current exceeds the specified limit, the power supply will be turned off. The power protection feature will turn off the power supply if the power consumption is more than the specified limit.

In conclusion, the FSQ100 AC-DC Conversion application field and working principle provides an effective solution for ac-dc conversion for offline switching applications. The device provides an adjustable output voltage, accurate temperature control, overvoltage and over-temperature protection and output current and power protection. All these features make the FSQ100 an ideal power solution for applications that require highly reliable and efficient power.
