Working Principle: The VIPER20ASPTR-E is a family of AC-DC and DC-DC switching power conversion devices that use a synchronous rectification process to achieve high efficiency and low input and output voltage drops. The device includes an internal high-side MOSFET and low-side MOSFET switch with dedicated dead time control logic and a bootstrap circuit. The source voltage is applied to the primary side of the transformer, which then generates an ac voltage on the secondary side. The power signal enters the VIPER20ASPTR-E, where the high-side and low-side MOSFET switches are driven at a frequency that is determined by a variable frequency oscillator (VFO). The signal is then rectified and filtered before being applied to the load.

The VIPER20ASPTR-E can be used in a variety of AC-DC and DC-DC applications, such as power supplies for automotive, industrial, and consumer electronic devices, DC motors and drives, data centers and telecommunications systems, and uninterruptible power supplies (UPS). By taking advantage of its high efficiency, high scalability, and ultra-low input and output voltage drops, it is able to deliver high power performance while being cost-effective.
