NOTES:

The output noise and ripple measurement was made with 20 MHz bandwidth using a 6 inch twisted pair, terminated with a 10 uF tantalum

capacitor in parallel with a 0.1 uF ceramic capacitor.

For ABC600-1048G/52G, the current share abs (I1-I2) should be less than 3 A at light load (< 25% of full load).

Figure 2. Output Power vs. Temperature

NOTE: Power darating linearly to 50% at 70ºC for the output including main output V1, Vfan.
