The Claf Power DFN1-F0505 is a high-performance 1W isolated DC/DC converter engineered to provide reliable and efficient power conversion for industrial, embedded, communication, and instrumentation applications. Operating from a 4.5V to 5.5V DC input, the converter delivers a regulated 5V DC output, making it an excellent solution for applications requiring electrical isolation while maintaining the same operating voltage. Its compact DIP package allows easy PCB integration into space-constrained electronic designs.

Designed with advanced switching technology, the DFN1-F0505 delivers typical efficiency up to 82%, ensuring reliable performance with minimal power loss. The converter provides 3000VDC galvanic isolation between the input and output circuits, protecting sensitive electronics from voltage spikes, reducing electromagnetic interference (EMI), and eliminating ground loop issues commonly encountered in industrial systems. The isolation barrier improves both safety and system reliability in demanding environments.

The module incorporates overload and continuous short-circuit protection, enabling safe operation during abnormal conditions. It also features low no-load current (<8mA) and low ripple and noise of approximately 30mVp-p, making it suitable for powering precision electronic circuits. The converter supports a wide operating temperature range from -40°C to +105°C, ensuring stable performance even under harsh environmental conditions.

Housed in a compact DIP package (12.7 × 10.16 × 8.2 mm), the DFN1-F0505 is ideal for automated PCB assembly and OEM product designs. It is widely used in industrial automation equipment, embedded controllers, communication systems, instrumentation, medical electronics, monitoring equipment, IoT devices, and isolated digital power supplies. With industrial-grade reliability, long service life, and high isolation performance, the DFN1-F0505 is an ideal power module for professional electronic applications.
