Notes
1. Measured at 300V nominal input.
2. Peak to peak measured at 20MHz bandwidth and i) 10μF al. and 1μF ceramic capacitor across output for 48V model
ii) 10μF tantalum and 1μF ceramic capacitor across output for all other models
3. Recommended input capacitance of 150μF required to reduce input ripple voltage at -40°C operation or 68μF for operation to -20°C. See application notes.
