The MAX5058 EV kit is a high-efficiency 50W isolated synchronous rectifier forward converter that uses an industrial standard 1/8 brick footprint. This evaluation board is configured for a +3.3V output and can provide up to 15A of output current. It is powered by +36V to +72V or -36V to -72V and can be used in telecommunications/data communications (48V modules), industrial or 42V automotive power systems.
This manual describes the Maxim MAX5058EVKIT evaluation board, a 50 W high‑voltage DC‑DC converter designed for ±36 V to ±72 V input and delivering a regulated +3.3 V/15 A output. Key parameters such as 250 kHz switching frequency, 89 % efficiency and 1/8 duty cycle are listed.
The document includes safety precautions for handling high‑voltage circuits, required external components (e.g., a 100 µF capacitor between +VIN and –VIN), a detailed bill of materials, wiring diagrams, and performance graphs to aid designers in integrating the board into their applications. This manual is written in Chinese.
| Switching frequency | 250 kHz |
|---|---|
| Output voltage tolerance | ±0.5 % |
