VIPERGAN65DTR

Overview

The VIPERGAN65DTR is an advanced quasi-resonant offline high voltage converter featuring an embedded E-mode GaN HEMT. Designed for medium-power applications, it supports ZVS flyback topologies with up to 65 W output power. The device integrates a 700 V GaN transistor and a low-voltage PWM controller in a single package. Key electrical characteristics include dynamic blanking time, valley synchronization, and input voltage feed-forward compensation. It offers comprehensive protection features such as OVP, OLP, brown-in/out, and iOVP, all operating in auto-restart mode.

• Enables zero-voltage switching via dynamic blanking and valley synchronization to maximize efficiency
• Provides advanced power management achieving ultra-low standby consumption through adaptive burst-mode
• Includes multiple auto-restart protection mechanisms for enhanced system safety and reliability

Applications

• Universal AC-DC adapters for consumer electronics
• USB Type-C Power Delivery chargers
• 24 V isolated power supplies
• High-efficiency offline SMPS designs

Procurement Notes

Verify the specific suffix DTR indicates the tape-and-reel packaging format when ordering. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to procurement. Ensure the component matches the required pinout and thermal specifications for the target PCB layout. Cross-reference the part number with the latest STMicroelectronics release notes to confirm current production status.

Selection Notes

Select this component for designs requiring high power density and efficiency in medium-power offline converters. The integrated GaN technology allows for reduced magnetics size compared to traditional silicon solutions. Consider the SO16n package option if surface-mount area is constrained. Evaluate the need for synchronous rectification on the secondary side to further optimize overall system efficiency at full load conditions.

Part Context

The VIPERGAN65 belongs to the VIPerGaN family, which transitions power conversion to 700 V GaN HEMT technology. This series enables ultra-compact designs with output powers ranging from 50 W to 100 W. Devices in this family are designed for pin-to-pin compatibility within specific groups, facilitating scalable power designs without extensive board redesigns.

Replacement Considerations

Check STMicroelectronics documentation for direct pin-compatible replacements within the VIPerGaN series. Verify that any substitute maintains the same 700 V rating and control interface. Ensure thermal performance and protection thresholds match the original design requirements.
