Overview
The VIPER222XSTR is a high-performance AC-DC converter integrating a 730 V avalanche-rugged power MOSFET with PWM control. It operates within a Vcc range of 4.5–30 V and features frequency jittering to spread EMI. The device achieves 40 mW no-load input power at 230 V AC through burst mode operation. It includes short-circuit protection, thermal shutdown, and a 1.2 V reference voltage. Operating temperature ranges from -25°C to 125°C in an SSOP-10 package.
Feature Summary
- Integrates a 730 V rugged power MOSFET with PWM controller
- Embeds high voltage startup and current sense circuitry
- Utilizes frequency jittering for EMI reduction
- Features burst mode for ultra-low no-load power consumption
Applications
- Mains power supplies up to 8 W
- Isolated flyback converters
- Universal input power applications (85–265 VAC)
Procurement Notes
Verify the specific suffix XSTR indicates tape and reel packaging when sourcing components. Confirm that the part number matches the SSOP-10 package format required for your design. Ensure compliance with industrial grade specifications and RoHS Ecopack2 standards before finalizing procurement orders.
Selection Notes
Select this component for designs requiring minimal external components due to embedded startup and sensing circuits. It is suitable for applications needing low standby power and compact EMI filtering solutions. Consider the 730 V switch rating for mains-connected offline power supply topologies.
Part Context
This device belongs to the VIPerPlus series of offline high-voltage converters from STMicroelectronics. It is designed for medium-power quasi-resonant ZVS flyback converters. The integration of the power switch and controller simplifies the bill of materials and reduces overall system size.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative models from the same family or competitor offerings.
