Overview
The VIPER12ADIP-E is a fixed frequency off-line converter from the VIPerPlus family, integrating a high voltage power MOSFET with a dedicated current mode PWM controller on a single silicon chip. It operates at a switching frequency of 60 kHz and supports a VDD supply range of 9 V to 38 V. The device features automatic burst mode for low load conditions and overvoltage protection in HICCUP mode. Typical power capability is 8 W for European input (195-265 Vac) and 13 W for wide-range input (85-265 Vac). It includes overtemperature, overcurrent, and overvoltage protection with auto-restart.
Feature Summary
- Integrates a rugged high voltage power MOSFET with a current mode PWM controller
- Features automatic burst mode operation to minimize input power consumption at light loads
- Includes comprehensive protection mechanisms such as thermal shutdown and overcurrent limiting with auto-restart
Applications
- Battery charger adapters
- Standby power supplies for televisions and monitors
- Auxiliary supplies for motor control systems
Procurement Notes
Verify that the specific part number suffix matches the required package type, as DIP-8 and SO-8 variants exist within the same product family. Confirm RoHS compliance status and ensure the ordering code aligns with the intended industrial temperature range specifications before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a compact solution with integrated high-voltage switching capabilities. Consider the fixed 60 kHz frequency when designing EMI filters. Ensure the auxiliary winding design accommodates the specified VDD voltage range to support reliable startup and operation under varying load conditions.
Part Context
This device belongs to the VIPerPlus family of high voltage converters designed for low-power offline switch-mode power supplies. It combines advanced control logic with robust power switching technology to reduce bill-of-materials count and system complexity while maintaining high efficiency and reliability standards.
Replacement Considerations
Direct substitutes include other members of the VIPerPlus family such as the VIPER12A-E series. Verify pin compatibility and thermal performance characteristics when transitioning between different package options or updated revisions within the manufacturer's portfolio.
