Overview
The VIPER50A(022Y) is an offline flyback converter from the VIPer™ series by STMicroelectronics, housed in a 5-PENTAWATT package. It integrates a high-voltage vertical power MOSFET with a PWM controller. The device supports switching frequencies up to 200 kHz and operates with a supply voltage range of 8V to 15V. Key electrical parameters include a breakdown voltage of 700V and a startup voltage of 11V. It provides up to 50W of output power and includes internal protections such as current limiting and over-temperature shutdown.
Feature Summary
- Integrates a high-voltage vertical power MOSFET with a state-of-the-art PWM circuit on a single silicon chip.
- Features automatic burst mode operation for low stand-by current consumption without external components.
- Includes built-in soft-start, frequency jittering for EMI suppression, and adjustable current limitation.
Applications
- Offline power supplies with secondary power capability up to 50W
- Adapters for consumer electronics
- General purpose AC-DC conversion
Procurement Notes
Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS3 compliance and check for alternative sources if immediate availability is required. Ensure proper handling for surface mount installation in Pentawatt packages.
Selection Notes
Select this component for designs requiring integrated high-voltage switching and compact form factors. Consider its fixed frequency capabilities and protection features for standard offline applications. Evaluate thermal management requirements for the Pentawatt package in enclosed spaces.
Part Context
Part of the VIPer™ family, combining power and control functions to reduce component count. Designed for cost-effective solutions in wide-range and single-range offline power supplies. Compatible with primary or secondary regulation loops.
Replacement Considerations
The VIPER50A-E is listed as an obsolete variant within the same product line. Verify pin compatibility and electrical specifications before substitution. No direct active substitutes are confirmed in the provided data.
