AC DC Converters, Offline Switches

VIPER53EDIP-E Description

The VIPER53EDIP-E from STMicroelectronics is a high-performance offline switch designed for flyback topology in AC/DC power conversion applications. This active, ROHS3-compliant device integrates an internal 620V breakdown voltage MOSFET, enabling robust operation with input voltages ranging from 8.4V to 19V and startup at 11.5V. Capable of delivering up to 50W of power with switching frequencies up to 300kHz, it is ideal for compact, high-efficiency designs. The isolated output ensures safety in demanding environments, while its through-hole 8DIP package simplifies integration.

VIPER53EDIP-E Features

• Integrated Power Switch: Combines a 620V MOSFET with control circuitry, reducing external component count.
• Advanced Control: Features frequency control, soft start, and enable (EN) pin for precise power management.
• Comprehensive Protection: Includes current limiting, over-load, over-temperature, and short-circuit protection for enhanced reliability.
• Wide Input Range: Operates from 8.4V to 19V, accommodating fluctuating supply conditions.
• High Switching Frequency: Supports up to 300kHz, enabling smaller magnetics and higher power density.
• REACH & MSL Compliant: REACH unaffected and MSL 1 (unlimited) for extended shelf life and environmental compliance.

VIPER53EDIP-E Applications

The VIPER53EDIP-E excels in offline power supplies for:

• Industrial Systems: PLCs, motor drives, and automation equipment requiring isolated, high-efficiency conversion.
• Consumer Electronics: Adapters, LED drivers, and appliances benefiting from its compact footprint and protection features.
• Telecom/Networking: Power modules for routers and base stations leveraging its wide input range and fault tolerance.
• Lighting: High-power LED ballasts where frequency control minimizes EMI.

Conclusion of VIPER53EDIP-E

The VIPER53EDIP-E stands out for its integration, robustness, and flexibility, making it a superior choice for 50W offline flyback converters. Its combination of protection features, high switching frequency, and ease of use positions it ahead of comparable ICs in cost-sensitive yet performance-critical applications. Engineers will appreciate its reliability in industrial, consumer, and telecom designs, backed by STMicroelectronics' proven quality.
