VIPER35LDTR

Overview

The VIPER35LDTR is an AC/DC converter from the VIPerPlus family, designed as a quasi-resonant high-performance offline high-voltage converter. It integrates an 800 V avalanche-rugged power MOSFET with a current mode PWM controller. The device supports isolated flyback topology and features a switching frequency limit of 136 kHz. It operates within a supply voltage range of 8.5 V to 23.5 V, delivering up to 22 W output power. The component utilizes SIOC-16 Narrow packaging for surface mount installation.

Feature Summary

Integrates an 800 V rugged power MOSFET with embedded high-voltage start-up and senseFET technology.
Employs quasi-resonant operation to reduce electromagnetic interference and improve power conversion efficiency.
Includes comprehensive protection mechanisms such as output overvoltage, short-circuit protection, and hysteretic thermal shutdown.
Supports low consumption standards by operating in burst mode under light load conditions.

Applications

Offline high-voltage power supplies
Isolated flyback converter designs
General-purpose AC/DC conversion systems

Procurement Notes

Verify the specific suffix 'L' confirms the 136 kHz frequency limit, distinct from other variants. Confirm the SIOC-16 Narrow package matches the design requirements. Ensure compliance with RoHS standards and check moisture sensitivity levels for proper handling. Validate that the 800 V rating aligns with the input voltage range specifications.

Selection Notes

Select this component for applications requiring high efficiency and low no-load consumption. The integrated MOSFET simplifies design by reducing external component count. Consider the 136 kHz frequency limit for EMI filtering requirements. The auto-restart feature after fault conditions enhances system reliability without manual intervention.

Part Context

The VIPER35LDTR belongs to the VIPerPlus family of high-voltage converters. This series is characterized by smart integration of power switches and control logic. The L variant specifically denotes the 136 kHz frequency limit, differentiating it from higher-frequency options within the same product line.
