DPA425SN Description

Short technical summary and product information.

The DPA425SN from Power Integrations is part of the DPA-Switch family, providing highly integrated DC-DC conversion solutions for applications such as Power over Ethernet (PoE) and telecommunications. This IC is designed for a wide input voltage range of 16-75 VDC, supporting both forward and flyback topologies.

 

Key electrical specifications include a maximum output power of 70W in a forward configuration and 52W in a flyback configuration, with a 220V integrated MOSFET. The device operates with pin-selectable switching frequencies of 300 kHz or 400 kHz. It features built-in auto-restart for overload protection and externally programmable current limit.

 

The DPA425SN is housed in a Surface Mount S-PAK package, suitable for high-power applications. It operates within a temperature range of -40°C to 125°C. The integration of components reduces board space and cost, making it an efficient solution for power management.

 

This IC is designed to eliminate external current sensing circuitry and includes features like line undervoltage detection meeting ETSI standards and hysteretic thermal shutdown for fault recovery. Its EcoSmart technology ensures energy efficiency with low no-load consumption.
