Notes to Specifications

1. Above +125

°C case temperature, derate output power linearly to 0 at +135°C case.

2. Recovery time is measured from the initiation of the input transient to where V

3. Turn-on delay time measurement is for either an application of power at the input or a signal at the inhibit pin.

4. Load current split equally between +V

5. Up to 90% of Full Power is available from either output provided. The total power output does not exceed 30 watts.

6. 3W load on output under test, 3W to 27W on other output.

7. Sync. Input signal: V
