Notes:
1. A future Application Note will detail the technique used to measure the reflected ripple current.
2. Refer to Power Derating Curve below for details on Output Current Derating with Ambient Temperature. A future Application Note will detail air flow
characterization.
3. Refer to performance curves section (pages 4 and 5) for variation in output ripple and noise with Ambient Temperature, Input Voltage and Output Current. The
unit requires a ceramic capacitor of 0.022µFacross measurement terminals. A future Application Note will detail measurement set up for output ripple and noise.
4. Refer to performance curves section for variation in efficiency against Input Voltage, Ambient Temperature, Output Load and Frequency.
