The DPA424SN-TL from Power Integrations is part of the DPA-Switch family, providing 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, integrating a high-frequency MOSFET and PWM control to reduce external component count and save space and cost.
Key electrical specifications include a wide input voltage range of 16-75 VDC and pin-selectable switching frequencies of 300 kHz or 400 kHz. Depending on the topology, it can deliver up to 35 W of output power in a forward configuration or up to 26 W in a flyback configuration, with output power limited by the device's internal current limit. The operating temperature range is -40°C to 125°C.
The DPA424SN-TL is available in a Surface Mount S-PAK package (SPak-7, 6 leads + Tab). It features integrated auto-restart for overload protection, externally programmable current limit, and line undervoltage detection meeting ETSI standards. The device also includes built-in soft-start for minimal stress and overshoot during power-up.
This IC is suitable for distributed power architectures, VoIP phones, WLAN devices, security cameras, and telco central office equipment. Its high integration and efficiency make it a cost-effective solution for demanding power conversion needs.
