6 Power-Up Procedure
1. Define which converters are to be enabled or disabled by connecting the correct jumpers accordingly.
2. Apply a DC voltage to jumper J8. Polarity is clearly marked on the silk-screen.
3. Verify that the relevant converters are powered up by the output voltages. The whole start-up process
will take less than 100 ms. PGOOD will be asserted high 32 ms after all converter outputs have
reached 90% of nominal voltages.
4. Apply loads to the output connectors (J9 and J11).
