Note: 1. The converter is not internally fused. An input line fuse such as Littlefuse 3AB type must be used.
2. Refer to Figure 1 for the external input capacitance required.
3. Refer to Figure 2 for output ripple and noise test measurement setup.
4. Output power derating applies at elevated temperature. Refer to Figure 11.
5. Refer to the output trim equations provided (Equations 1 and 2).
6. For temperature greater than -20°C, minimum pin disable time is 100ms.
For temperature less than -20°C, minimum pin disable time is 1s.
