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
Power Feedback Input. See the PWFBOUT description above.
