DPA425SN-TL

Special Purpose Regulators Overview

The DPA425SN-TL is an isolated DC-DC converter from the DPA-Switch family, designed for distributed power architectures. It accepts a wide input voltage range of 16 V to 75 V DC and provides a single fixed output channel at 16 V. The device delivers an output power of 70 W with an output current of 4.3 mA. It utilizes a thermally efficient TO-263-7C (SPAK) surface-mount package. The component operates within a temperature range of -40 °C to +150 °C and supports flyback topology.

Special Purpose Regulators Feature Summary

• Integrates a high-frequency MOSFET, PWM control, and fault protection onto a single CMOS chip
• Includes built-in auto-restart for output overload and open-loop protection
• Features externally programmable current limit and pin-selectable switching frequency
• Supports synchronous rectification through line undervoltage and overvoltage detection

Special Purpose Regulators Applications

• Distributed power supply systems
• Industrial control equipment
• Telecommunications infrastructure

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'TL' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required thermal management capabilities for the intended application environment. Cross-reference the part number with the latest datasheet revision to confirm compliance with current regulatory standards such as ETSI.

Special Purpose Regulators Selection Notes

Select this component for applications requiring high integration and reduced external component count in low-to-medium power designs. The wide input voltage range suits direct bus conversion without intermediate regulation. Consider the SPAK package for its thermal efficiency compared to standard plastic DIP options when higher power densities are required.

Special Purpose Regulators Part Context

This device belongs to the DPA-Switch family, which offers highly integrated solutions for DC-DC conversion. The family eliminates up to 50 external components by integrating power switching and control circuitry. The DPA425 variant specifically targets applications needing higher output power while maintaining the cost-effective and compact form factor characteristic of the series.
