VIPERGAN100TR

Overview

The VIPERGAN100TR is an advanced quasi-resonant offline high voltage converter integrating a 650 V E-mode GaN HEMT. Designed for medium power applications, it delivers up to 75 W in wide-range inputs and up to 100 W in European ranges or with front-end PFC. The device features dynamic blanking time and adjustable valley synchronization to maximize efficiency across all load conditions. It includes embedded sense FETs, output overvoltage protection (OVP), overtemperature protection (OTP), overload protection (OLP), and brown-in/out protection, all operating in auto-restart mode.

Feature Summary

Integrates a 650 V E-mode power GaN transistor with an advanced quasi-resonant flyback controller.
Features dynamic blanking time and valley synchronization functions to minimize switching losses and maximize efficiency.
Includes comprehensive protection mechanisms such as OVP, OTP, OLP, and brown-in/out protection for enhanced safety.

Applications

Medium power quasi-resonant ZVS flyback converters
USB-PD chargers and adapters
Home appliances and smart building controllers
Industrial equipment power supplies

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the component status as NRND (Not Recommended for New Designs) in official STMicroelectronics documentation before finalizing any new design implementations. Ensure compatibility with existing board layouts if substituting from previous revisions of the VIPERGAN family.

Selection Notes

Select this component for designs requiring high power density and efficiency in the 75 W to 100 W range. It is suitable for applications needing integrated GaN technology without external gate drivers. Consider the NRND status for long-term supply chain planning. Evaluate the need for front-end PFC if targeting full European range input specifications for maximum output power.

Part Context

The VIPERGAN100 belongs to the VIPERGAN series, which marks the transition to 700 V GaN HEMT technology. This family offers pin-to-pin compatibility across devices, allowing for scalable power designs without PCB redesign. The series targets applications demanding superior performance through high switching frequencies and minimized magnetic components.
