FSCQ1265RTYDTU is a high-performance PMIC (Power Management Integrated Circuit) AC/DC (Alternating/Direct Current) Converter, Offline Switcher that works with an advanced Zero Voltage Transition (ZVT) Boost converter architecture. The device is designed to convert AC line voltages from a wide range of input voltage sources, such as 110VAC to 220VAC and 220VAC to 110VAC, into an adjustable DC output voltage.

The FSCQ1265RTYDTU AC/DC Converter, Offline Switcher offers advanced features such as: high switching frequency, high efficiency, low losses, ZVT topology, and a wide operating temperature range. The device is available in three different package options, SO8, and 3.3 x 3.3mm QFN as well two different voltage ratings, 12V and 15V.

The operating principle behind the FSCQ1265RTYDTU PMIC AC/DC Converter, Offline Switcher is based on the ZVT topology converter. When current flow is initiated in the primary winding of the transformer, the magnetic field that is created thereby induces a voltage in the secondary winding of the transformer. The voltage induced in the secondary winding is proportional to the voltage present in the primary winding, provided that the turns ratio of the transformer is maintained.

The FSCQ1265RTYDTU PMIC AC/DC Converter, Offline Switcher takes advantage of the transformation of energy from one form to another. The primary winding of the transformer is connected to the AC mains supply and the secondary winding is connected to a power switch mounting integrated circuits or a Darlington transistor. As the current flow in the primary winding changes, the voltage induced in the secondary winding is forced to switch state, thus allowing the power switch to turn on and off rapidly. This switching of the power switch produces the desired output voltage.

The Zero Voltage Transition (ZVT) architecture of FSCQ1265RTYDTU PMIC AC/DC Converter, Offline Switcher further enhances the efficiency of the conversion process. By controlling the commutation of the power switch, the ZVT feature ensures that the input power to the switch is zero when it switches state. This prevents conduction losses in the switch, thus leading to very efficient power conversion and improved power factor.

The FSCQ1265RTYDTU PMIC AC/DC Converter, Offline Switcher is suitable for a variety of applications, including LED lighting systems, motor control, industrial automation, and various industrial electronics applications. The device’s advanced design and wide operating temperature range make it ideal for high powered applications that require higher efficiency and reliability. The high performance, zero voltage transition architecture, makes the FSCQ1265RTYDTU PMIC AC/DC Converter, Offline Switcher a great choice for applications requiring high efficiency and power factor correction.
