Power Integrations 1-Channel Highly Integrated DC/DC Converter IC, Fixed 8-Pin DIP-B DPA423PN

Power Integrations DPA423PN is a highly integrated 1-channel DC/DC Converter IC designed for efficient power management in industrial and telecommunication applications. It is optimized for input voltages ranging between 16 and 75 V DC, making it suitable for a wide variety of equipment requiring robust power conversion.

This fixed output converter features an 8-pin DIP-B package suitable for through-hole mounting, providing ease of integration into PCB designs. It supports a maximum switching frequency of 425 kHz, enabling compact and efficient power circuits.

The device includes advanced features such as lossless integrated current limiting, built-in auto-restart functionality after fault conditions, and input undervoltage and overvoltage protection to ensure operational reliability. Hysteretic thermal shutdown further protects the IC under extreme temperature conditions.

With precise control over critical parameters including current limit, frequency, and PWM gain, the DPA423PN simplifies design efforts and enhances performance consistency over wide temperature ranges (-40°C to 150°C).

Its robust specifications make it ideal for power modules in power over Ethernet (PoE) powered devices, network servers, routers, telecom central office equipment, VoIP and digital feature phones, as well as industrial temperature and process control systems.

This IC supports a minimum input voltage of 36 V DC and a maximum input voltage of 75 V DC. Fixed output type and one output channel provide stable voltage regulation. Maximum switching frequency up to 425 kHz improves power conversion efficiency.

8-pin DIP-B through-hole package facilitates standard PCB assembly. Wide operating temperature range from -40°C to 150°C supports industrial environments. Compliance with RoHS and ETSI standards ensures environmental and electromagnetic compatibility.

Integrated lossless current limit and built-in auto-restart enhance device safety and durability. Input undervoltage/overvoltage shutdown protects against extreme power conditions. User-configurable pins and hysteretic thermal shutdown provide design flexibility and thermal protection.

Suitable for telecommunications, industrial controls, network equipment, and PoE devices.
