PMIC - AC DC Converters, Offline Switchers typically refer to a class of power management integrated circuits or PMICs, which are also known as Regulated DC-to-DC Converters. The FSCQ1565RTYDTU is an offline switcher integrated circuit specifically devised for non-isolated, constant-frequency current mode offline applications, such as in battery-powered products like mobile phones, notebook computers, and digital cameras.

Application Field of FSCQ1565RTYDTU

The FSCQ1565RTYDTU is an ideal PMIC with a wide input voltage range from 4.5 V to 25 V, allowing it to be widely used in multiple offline power supply applications. It provides a constant current frequency up to a maximum of 400 kHz, offering a low quiescent current to provide efficient power management in the given operating temperature range of -40 °C to 125 °C. This PMIC offers protection against high-voltage transients, over-current and over-temperature, thus making it suitable for consumer electronic products that require high application safety. Moreover, the FSCQ1565RTYDTU is RoHS, KCC, and UL compliant and is designed to meet the stricter requirements of SELV and EN 60950 standards.

Working Principle of FSCQ1565RTYDTU

The FSCQ1565RTYDTU is an integrated circuit based on a multiphase control architecture, which is essentially a combination of MOSFETs, inductors, and capacitors arranged in a network with synchronous rectifiers. It works as a linear voltage regulator to convert AC (Alternating Current) to DC (Direct Current) for different applications. It comprises of two key parts – primary and secondary. The primary part consists of a schematic representation comprising of two power MOSFETs (Metal Oxide Semiconductor Field-Effect Transistor) operated in complementary mode, connected to a transformer through the primary windings and is designed to handle the input current. The secondary part comprises of a bridge rectifier that is connected to the transformer\'s secondary coils, a power MOSFET and a filter capacitor. The power MOSFET is operated in the “on” state when the current reaches a certain level, and this supplies the load with the required power. The output voltage of the FSCQ1565RTYDTU is usually steady and regulated, and achieves this by changing the duty-cycle at which the primary power MOSFET switches.

Conclusion

The FSCQ1565RTYDTU is a powerful and integrated PMIC for offline applications, covering a wide range of input voltages and output current ranges. This PMIC effectively reduces electromagnetic interference in SELV and EN 60950 compliant applications and is stable over a wide temperature range. Moreover, it provides protection against high-voltage transients, over-current and over-temperature, thereby offering high application safety. It works on a constant frequency current mode architecture and a power MOSFET is operated in the “on” state when the current reaches a certain level to supply power to the load. This makes the FSCQ1565RTYDTU an ideal PMIC for AC-DC converter and offline switcher applications.
