VIPER16HDTR

Overview

The VIPER16HDTR is an offline converter from the VIPerPlus family, featuring a high-voltage avalanche rugged power section and integrated PWM controller. It operates at a fixed switching frequency of 115 kHz with a maximum duty cycle of 80%. The device supports Buck-Boost and Flyback topologies and includes an internal switch rated for 800 V breakdown voltage. It functions within a supply voltage range of 11.5 V to 23.5 V and delivers up to 10 W of output power. The component is housed in a 16-SO package and operates across a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates an 800 V avalanche rugged power section with a PWM controller for direct mains powering without auxiliary windings.
• Features hysteretic thermal protection and safe auto-restart capabilities following fault conditions.
• Utilizes advance frequency jittering to reduce electromagnetic interference filter costs.

Applications

• Offline AC/DC converters
• Buck-Boost topology power supplies
• Flyback topology power supplies

Procurement Notes

Verify the specific suffix 'H' indicates the 115 kHz operating frequency variant distinct from other family members. Confirm the 16-SO package dimensions match the design footprint requirements. Ensure the application environment stays within the specified -40°C to 150°C junction temperature limits. Validate that the 800 V breakdown rating suits the input voltage stress conditions.

Selection Notes

Select this component when a higher switching frequency of 115 kHz is required compared to the 60 kHz variants in the same family. It is suitable for applications needing self-powering from rectified mains without auxiliary bias windings. Consider the 16-SO package constraint for PCB layout. Verify compatibility with Buck-Boost or Flyback topologies for the intended power level.

Part Context

This part belongs to the VIPerPlus series of energy-saving high-voltage converters. It shares core architectural features with other VIPER16 models but differs in switching frequency specifications. The series emphasizes low standby power consumption and simplified design by eliminating auxiliary winding requirements for low-power applications.

Replacement Considerations

The VIPER16HD is a verified equivalent substitute part number offering identical electrical characteristics and functionality.
