1. Specifications over the -40°C to +85°C operating temperature range are assured by design, characterization and correlation with sta-
tistical process controls.
2. Maximum output power and current is dependent upon operating efficiency and thermal/mechanical design. Output current and out-
put power derating may apply. See Figure 1.
3. Total input current with prescribed FB resistor network can be reduced with larger resistor values.
