The VIper35HD is a power management integrated circuit (PMIC) technology made specifically to manage high-level AC/DC conversions, offline switching, and other power activities. Developed by Ixys Corporation, the VIper35HD operates in the approximate range of -25°C to +125°C and works to provide a robust, highly efficient solution to many applications that require AC/DC expansions, including private and public sector, energy, and industrial installations.

When speaking of its typical applications, the VIper35HD is well-suited for many industrial, commercial, and consumer-level industrial equipment. Among the industries this PMIC has found a home are PLCs, industrial printers, ATMs, computers, communications, servers, HVAC systems, and medical equipment. Additionally, the VIper35HD can be combined with other ICs to handle slightly different requirements, such as mixed-signal motor control as well as advanced power modeling.

This PMIC is praised for having the capability to handle hundreds of watts of power while providing a highly efficient operation with low component counts. In terms of working principles, the VIper35HD uses a two-stage architecture, which involves the integration of two power component processes. The first component is the preregulator, which is responsible for control, regulation, and rectification of both lines and neutral of the incoming AC power to generate an output DC voltage (usually refer to as VDC). This DC voltage is used by the second component, which is the dc-to-dc stage process (also referred to as VDC), to convert the VDC input into multiple regulated, DC output voltages.

Among the design features of the VIper35HD are low component counts, reduction of heat sinking, and more space for cost efficiency. As for the VIper35HD PMIC’s functional specifications, these include output voltage accuracy, AC line and neutral voltage, power supply line voltage tolerance, synchronization, and also soft start power sequencing. The VIper35HD technology offers a broad range of fault protection capabilities and has proven to be suitable for multiple applications.

The VIper35HD is highly reliable and robust, offering excellent thermal performance. With its two-stage architecture, the efficiency of this power management is greater than 85%. This integrated circuit PMIC also offers an excellent protection feature, which guards users from such abnormalities as over-voltage, over-current, and short-circuit faults. In conclusion, it is clear that the VIper35HD is a powerful PMIC that offers solutions to multiple AC/DC conversion scenarios, making it a beneficial technology for many different applications.
