CAUTION: This converter is not internally fused. An input line fuse must be used in application.

Recommend a fast-acting fuse with maximum rating of 18A on system board. Refer to the fuse

manufacture’s datasheet for further information.

Notes: 1. This converter has internal C-L-C (0.47uF-0.47uH-8.8uF) filter.

2. All specifications are typical at 25 °C unless otherwise stated.
