Overview
The VIPER16LDTR is an offline switcher from the VIPerPlus series, integrating a high-voltage power MOSFET and control circuitry in a single package. It operates at a fixed switching frequency of 60 kHz with a maximum duty cycle of 70%. The device supports buck, buck-boost, and flyback topologies. Key electrical parameters include a breakdown voltage of 800 V, a supply voltage range of 11.5 V to 23.5 V, and a startup voltage of 13 V. It delivers up to 10 W of output power and functions within a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates an avalanche-rugged 800 V power section for robust operation.
- Includes built-in current limiting with adjustable set points and thermal shutdown protection.
- Features frequency jittering to reduce electromagnetic interference (EMI).
- Supports non-isolated applications with low standby consumption capabilities.
Applications
- Non-isolated DC/DC converters
- Buck and buck-boost power supplies
- Flyback AC/DC converters
- Smart grid distribution systems
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the component matches the official STMicroelectronics datasheet specifications for the VIPerPlus series. Ensure compatibility with the required 16-SOIC surface-mount footprint during procurement planning.
Selection Notes
Select this component for designs requiring integrated high-voltage switching without external discrete components. It is suitable for applications needing fixed-frequency operation at 60 kHz. Consider its suitability for non-isolated topologies where cost reduction through simplified supply networks is prioritized.
Part Context
This part belongs to the VIPerPlus family of high-voltage AC-DC converters. It is designed to replace older discrete solutions by combining the power MOSFET and controller into one unit. The device is manufactured by STMicroelectronics and is intended for energy-efficient power conversion tasks.
Replacement Considerations
The VIPER15LDTR is listed as a discontinued direct substitute option. Verify functional equivalence regarding topology support and pinout compatibility before implementation.
