Overview
The VIPER37LE is an offline converter from the VIPerPlus family, designed for high-performance AC/DC conversion. It features a rugged 800 V power section and PWM control with adjustable limiting current. The device includes two levels of overcurrent protection, output overvoltage protection, hysteretic thermal shutdown, and safe auto-restart. It operates at a fixed frequency with advance jittering to reduce EMI. Standby consumption is 30 mW at 265 V ac. The component utilizes a 10-pin SDIP package.
Feature Summary
- Integrates an 800 V avalanche-rugged power MOSFET for ultra-wide range input voltage capability.
- Provides comprehensive protection including dual overcurrent, overvoltage, overload, and hysteretic thermal shutdown.
- Features advanced frequency jittering to minimize electromagnetic interference filter costs.
- Includes embedded high-voltage startup circuit and onboard soft-start functionality.
Applications
- Wide-range single-output mains power supplies
- Offline high-voltage converters
- AC/DC power management systems
Procurement Notes
Verify the specific suffix 'LE' against official STMicroelectronics documentation to confirm pinout and package configuration. Ensure compatibility with the intended thermal management requirements due to the SDIP packaging. Cross-reference the datasheet for exact operating temperature ranges and electrical limits before integration into the final design.
Selection Notes
Select this component for applications requiring robust high-voltage handling and low standby power consumption. The integrated protections simplify design complexity by reducing external component count. Consider the fixed frequency operation and jittering capabilities when designing the EMI filter stage for compliance with regulatory standards.
