VIPER50ASP

Overview

The VIPER50ASP is an offline converter from the VIPER series, utilizing a flyback topology with a maximum switching frequency of 200kHz. It features an internal high-voltage switch with a breakdown voltage of 620V and operates within a supply voltage range of 8V to 15V. The device includes startup voltage at 11V and provides fault protection through current limiting and over-temperature mechanisms. Packaged in a 5-PENTAWATT surface-mount configuration, it supports isolated output applications.

Feature Summary

• Integrates a high-voltage vertical power MOSFET with PWM control circuitry on a single silicon chip
• Provides comprehensive fault protection including current limiting and over-temperature shutdown
• Supports burst mode operation for low standby power consumption without additional components

Applications

• Offline power supplies with secondary power capability up to 50W
• Wide-range AC-DC converters
• Single-range or doubler configuration power adapters

Procurement Notes

Verify component authenticity and datasheet alignment due to obsolete status. Confirm RoHS compliance requirements as specific variants may differ. Check for authorized distribution channels given end-of-life designation. Ensure package integrity matches the 5-PENTAWATT specification during inspection.

Selection Notes

Select this component for designs requiring integrated high-voltage switching and control in a compact form factor. Consider the 620V breakdown rating for appropriate voltage headroom. Evaluate thermal management needs for the Pentawatt package. Compare against newer generations if long-term availability is critical for production runs.
