The DPA423PN from Power Integrations is part of the DPA-Switch family, offering highly integrated DC-DC conversion solutions for applications requiring 16-75 VDC input. This IC is designed for Power over Ethernet (PoE) and Telecom applications, simplifying designs by integrating a high-frequency MOSFET, PWM control, and fault protection.
Key electrical specifications include a wide input voltage range of 16-75 VDC and pin-selectable operating frequencies of 300 kHz or 400 kHz. The device supports both forward and flyback topologies, with maximum output power ratings up to 12W in forward mode and 9W in flyback mode from a 36-75 VDC input. Device dissipation is rated at 0.5W for both modes under specific conditions.
The DPA423PN is housed in an 8-DIP package, suitable for through-hole mounting. 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 demanding power conversion tasks in telecom infrastructure and PoE-enabled devices.
This IC offers features such as built-in auto-restart for overload protection, externally programmable current limit, and line undervoltage detection meeting ETSI standards. Its EcoSmart technology ensures energy efficiency with low no-load consumption and cycle skipping at light loads.
