DPA423G-TL

Special Purpose Regulators Overview

The DPA423G-TL is a highly integrated DC-DC converter IC from the DPA-Switch family by Power Integrations. It features an isolated single output with a maximum power of 13 W. The device accepts a wide input voltage range of 16 V to 75 V DC and provides a fixed 16 V output at 2.3 mA. Packaged in an SMD-8 surface-mount format measuring 9.32 mm x 6.1 mm x 3.18 mm, it operates within a temperature range of -40°C to +150°C.

Special Purpose Regulators Feature Summary

• Integrates a 220 V high-frequency MOSFET with PWM control circuitry
• Eliminates external current sensing components through built-in limiters
• Includes auto-restart protection for output overload and open-loop conditions

Special Purpose Regulators Applications

• Power over Ethernet (PoE) applications
• Telecom central office equipment
• Distributed power structure DC-DC converters

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'G' against official manufacturer documentation to confirm package type and pinout compatibility. Ensure design requirements align with the specified 16 V fixed output and 13 W power limit. Confirm thermal management strategies for the SMD-8 package given the high operating temperature rating.

Special Purpose Regulators Selection Notes

Select this component for designs requiring a compact, highly integrated solution for low-power isolated conversion. It is suitable for applications where minimizing external component count and board space is critical. Verify that the 16 V fixed output meets system requirements without additional regulation needs.

Special Purpose Regulators Part Context
