Notes: 1. Maximum combined power.
2. 10% minimum load is required to maintain the ripple and regulation.
3. Ripple and noise is measured from 10 KHz to 20 MHz at output terminals with a 0.1 μF ceramic capacitor and a 22 μF electrolytic capacitor in parallel.

Designated as PG on the CN1. This signal goes high 100-500 mS after the output reaches regulation.
It goes low at least 1 mS before loss of regulation.
fan drive 12 Vdc / 400 mA for external fan
