Overview
The VIPER20-22-E is an AC/DC converter from the VIPerPlus family by STMicroelectronics, integrating a high-voltage power MOSFET with a current-mode PWM controller. It supports flyback topology and operates at switching frequencies up to 200 kHz. The device features an internal 620 V breakdown voltage and includes protections against overcurrent and thermal overload. Designed for low-power applications, it offers isolated output conversion with minimal external component requirements.
Feature Summary
- Integrates a high-voltage avalanche-rugged power MOSFET with a current-mode PWM controller
- Supports flyback topology with integrated error amplifier and oscillator
- Includes built-in protection mechanisms such as current limit and thermal shutdown
Applications
- Offline switchers for low-power AC/DC converters
- Flyback power supply designs
- General-purpose isolated DC-DC conversion
Procurement Notes
Verify the specific suffix (e.g., DIP or STR) to confirm package type and pinout compatibility. Ensure the selected variant matches the required isolation and thermal specifications for the target application. Cross-reference official datasheets for exact electrical limits before integration.
Selection Notes
Select based on required input voltage range and output power needs within the VIPerPlus family. Consider the operating temperature range and packaging style suitable for the assembly process. Verify that the integrated protections meet the safety standards of the end equipment.
Part Context
Part of the VIPerPlus series, designed for cost-effective and compact power solutions. Combines high-voltage technology with advanced control logic to reduce bill of materials. Widely used in consumer electronics and industrial adapters requiring reliable offline conversion.
Replacement Considerations
Check for direct pin-compatible substitutes within the same VIPerPlus family. Verify equivalent breakdown voltage and switching frequency characteristics. Confirm that alternative parts support the same flyback topology and protection features.
