DPA424G

Special Purpose Regulators Overview

The DPA424G is an isolated DC-DC converter from the DPA-Switch family, designed for Power over Ethernet and telecom applications. It features a wide input voltage range of 16 V to 75 V DC and provides a single fixed output channel at 16 V with a maximum current of 3 mA. The device supports up to 35 W of output power and operates within a temperature range of -40 °C to +150 °C. It utilizes an 8-pin SMD package with dimensions of 9.32 mm in length, 6.1 mm in width, and 3.18 mm in height.

Special Purpose Regulators Feature Summary

• Integrates a 220 V high-frequency MOSFET and PWM control to eliminate external current sensing circuitry
• Includes built-in auto-restart protection for output overload and open loop conditions
• Features source-connected tab design to reduce electromagnetic interference

Special Purpose Regulators Applications

• Power over Ethernet (PoE) systems
• Telecom equipment power supplies
• Industrial isolated DC-DC conversion

Special Purpose Regulators Procurement Notes

Verify the specific suffix against official documentation, as variations such as GN-TL indicate surface mount packaging while PN indicates through-hole DIP. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure the selected variant matches the required thermal management and assembly method for the target application.

Special Purpose Regulators Selection Notes

Select this component for designs requiring a highly integrated solution that reduces external component count by up to 50 percent. It is suitable for applications needing a wide input voltage range and robust protection features without complex external control loops. Consider the package type based on the available board space and manufacturing capabilities.

Special Purpose Regulators Part Context

This part belongs to the DPA422-426 series, which offers plastic DIP, surface mount, and TO-263 options for power levels up to 35 W. The series is engineered to meet ETSI standards for line undervoltage detection. It serves as a compact alternative to discrete solutions in space-constrained industrial and communication hardware.
