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
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 after 256 ms.
4. Apply loads to the output connectors.
5. To power the USB switch apply a suitable voltage to jumper 27 and enable the switch by connecting
5. To power the USB switch apply a suitable voltage to jumper 27 and enable the switch by connecting
JP25 to 3V3 or leave it open.
