Table 8. Reset and Other Pins

Description

RESETB.

Set low to reset the chip. For a complete reset, this pin must be asserted low

for at least 10ms.

Power Feedback Output.

Be sure to connect a 22uF tantalum capacitor for frequency compensation and

a 0.1uF capacitor for noise de-coupling. Then connect this pin through a

ferrite bead to PWFBIN (pin8). The connection method is outlined in

7.11 3.3V Power Supply and Voltage Conversion Circuit, page 22.

Power Feedback Input. See the PWFBOUT description above.

Not Connected.
