VIPER53DIP-E

Overview

The VIPER53DIP-E is an offline switch integrating a high voltage MDMesh power MOSFET with an enhanced current mode PWM controller in an 8-DIP package. It supports flyback topologies with switching frequencies up to 300kHz and a breakdown voltage of 620V. The device provides 50W output capability in single European voltage ranges or 30W in wide range inputs. Operating parameters include a supply voltage (Vcc/Vdd) range of 8.4V to 19V, a start-up voltage of 11.5V, and a junction temperature range from -40°C to 150°C.

Feature Summary

• Integrates high voltage MDMesh power MOSFET with current mode PWM controller
• Includes automatic burst mode for efficient standby operation
• Features overload and short-circuit control via feedback monitoring
• Provides primary regulation protection through high gain error amplifier

Applications

• Offline power supplies with secondary power capability up to 30W
• Power supplies requiring 50W in single European voltage ranges
• Industrial tools and motor drives
• Smart grid distribution equipment

Procurement Notes

Verify the specific suffix 'DIP' confirms the through-hole 8-DIP package variant rather than surface mount options. Confirm RoHS compliance status matches project requirements. Check datasheet revisions for any updates to electrical characteristics or pinout definitions before finalizing design integration.

Selection Notes

Select this component when designing flyback converters requiring integrated high voltage switching without external heat sinks for moderate power levels. The fixed frequency operation suits applications where EMI filtering costs must be minimized. Ensure input voltage ranges align with the specified 85V to 265VAC operational limits for optimal performance.

Part Context

Part of the VIPER™ family of smart offline switches combining power MOSFETs with control logic. Designed to reduce component count and system size by integrating startup sources, protection circuits, and oscillators into a single monolithic package suitable for cost-sensitive AC-DC conversion designs.

Replacement Considerations

The VIPER53EDIP-E serves as a related variant within the same series. Verify if secondary regulation requirements necessitate the extended VDD voltage range offered by the EDIP version over the standard DIP configuration.
