Power Integrations 5-Channel Adjustable DC/DC Converter 3.5 A 7-Pin TO-263 DPA424R-TL

Power Integrations DPA424R-TL is a highly integrated 5-channel adjustable DC/DC converter IC designed specifically for Power over Ethernet (PoE) and telecom DC/DC applications. This device integrates a 220V power MOSFET with pulse width modulation (PWM) control on a single CMOS chip, resulting in cost-effective, compact designs.

The converter supports a minimum input voltage of 36V and a maximum of 75V dc, with a maximum output current of 3.5 A distributed across five independent outputs. Its flyback topology provides efficient power conversion across a maximum switching frequency of 425 kHz, which allows for superior transient response and smaller external components. The device offers through-hole mounting with a TO-263 package type, measuring 9.83 mm in length, 6.6 mm in width, and 3.68 mm in height.

Designed for applications including VoIP phones, WLAN equipment, and security cameras, the DPA424R-TL features built-in auto-restart mechanisms to protect against output overload and open loop conditions. Additionally, it has a hysteretic thermal shutdown feature that ensures automatic recovery from faults, making it well suited for robust industrial, telecommunications, and networking environments.

Operating reliably in temperatures from -40°C to 150°C, this IC does not conform to automotive standards and carries no specific certifications. Its compact form factor and integrated system design reduce overall solution size and bill of materials, making it ideal for cost-sensitive and space-constrained electronic designs.
