Notes

1. Measured before Input Filter.

2. Scope measurement should be made using a BNC connector with 1uF and 10uF aluminum electrolytic capacitor across output. Scope set to read at 20MHz bandwidth.

3. 25%-50%-75% load, 0.1/uS.

4. The Cold Start condition is a uniform converter temperature of -40°C after thermal stabilization. An additional 2x220uF is needed for cold startup conditions. The Hot Start condition for start up is a uniform converter temperature of 65°C after thermal stabilization.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted.
