Overview
The VIPER53SPTR-E is a high-voltage offline switch from STMicroelectronics, integrating an enhanced current mode PWM controller with a high voltage MDmesh power MOSFET in a single PowerSO-10 package. It supports flyback topology with a switching frequency up to 300 kHz and a breakdown voltage of 620 V. The device delivers up to 40 W output power, operates on a supply voltage range of 9.3 V to 17 V, and consumes only 9 mA during operation. It features automatic burst mode for low standby consumption and includes comprehensive protection mechanisms such as overtemperature shutdown and short-circuit control.
Feature Summary
- Integrates an enhanced current mode PWM controller with a high voltage MDmesh power MOSFET
- Features automatic burst mode for efficient standby conditions compliant with Blue Angel standards
- Includes overload and short circuit control managed by feedback monitoring
- Provides primary regulation or secondary loop failure protection via a high gain error amplifier
Applications
- Offline power supplies requiring secondary power capability up to 30W in wide range input voltage
- Power supplies operating in single European voltage ranges
- Industrial tools and motor drives
- General equipment power systems
Procurement Notes
Verify the specific suffix 'PTR' indicates tape-and-reel packaging when sourcing components. Confirm the active status of this variant against official STMicroelectronics documentation, as availability may vary by region. Ensure the PowerSO-10 package dimensions match your PCB layout requirements before finalizing procurement decisions.
Selection Notes
Select the VIPER53SPTR-E for designs requiring surface mount integration within the VIPer53 family. This variant offers the same electrical performance as through-hole versions but utilizes a PowerSO-10 package suitable for automated assembly. Consider its 620V breakdown voltage and 40W power handling capabilities for compact offline converter designs.
Part Context
The VIPER53SPTR-E belongs to the VIPer53 series of AC/DC converters manufactured by STMicroelectronics. This series represents state-of-the-art primary side switches designed for cost-effective and high-performance offline power supply applications. The component integrates advanced protection features and high-voltage MOSFET technology to simplify design and improve reliability.
Replacement Considerations
The VIPER53EDIP-E and VIPER53ESP-E are documented variants within the same product family. Verify pin compatibility and package differences (DIP-8 vs. PowerSO-10) when substituting these parts.
