VIPER32DIP

Overview

The VIPER32DIP is an enhanced current mode PWM controller integrated with a high-voltage MDmesh power MOSFET in a DIP-8 package. It functions as a fixed-frequency offline converter designed for secondary power supplies up to 30W in wide-range input applications or 50W in single European voltage ranges. Key operational features include overload and short-circuit control via feedback monitoring, efficient standby mode through enhanced pulse skipping, and primary regulation protection using a high-gain error amplifier. The device incorporates a high-voltage start-up current source, undervoltage lockout with hysteresis, automatic burst mode for Blue Angel compliance, overtemperature protection, and soft-start capabilities.

Feature Summary

• Integrates an enhanced current mode PWM controller with a high-voltage MDmesh power MOSFET within a single DIP-8 package.
• Provides overload and short-circuit protection controlled by feedback monitoring with delayed device reset.
• Achieves efficient standby operation through enhanced pulse skipping mechanisms.
• Includes primary regulation and secondary loop failure protection via a high-gain error amplifier.

Applications

• Offline power supplies with secondary power capability up to 30W in wide-range input voltage
• Offline power supplies with secondary power capability up to 50W in single European voltage range

Procurement Notes

Verify the specific suffix 'DIP' confirms the dual-in-line package configuration required for your assembly process. Confirm that the component meets the necessary regional compliance standards for the target market. Ensure the design accommodates the thermal requirements associated with the DIP-8 package under maximum load conditions. Cross-reference the official datasheet for exact pinout definitions and absolute maximum ratings before finalizing procurement.

Selection Notes

Select this component when designing offline power supplies requiring a compact solution with integrated power switching. It is suitable for applications needing primary regulation and robust protection against short circuits and overloads. Consider its suitability for wide-input or single European voltage ranges based on the specific power output requirements of the system.

Part Context

The VIPER32DIP belongs to the VIPER family of high-voltage switchers from STMicroelectronics. This series combines PWM controllers with power MOSFETs to simplify offline power supply designs.
