SOURCE
(S)
The power MOSFET drain connection provides internal
operating current for both start-up, steady-state and Power-
Down mode operation.

BYPASS/MULTI-FUNCTIONAL (BP/M) Pin:
An external bypass capacitor, 0.1 m F or greater for the internally
generated 5.85 V supply is connected to this pin. The minimum
value of capacitor is 0.1 m F for internal circuit operation. Higher
values may be required to enter Power-Down mode (see
LinkZero-AX Power-Down (PD) Mode Design Considerations).

An overvoltage protection disables MOSFET switching if the
current into the pin exceeds 6.5 mA (I SD ).
FEEDBACK (FB) Pin:
3a
3b
PI-5910-090810
During normal operation, switching of the power MOSFET is
controlled by this pin. MOSFET switching is disabled when a
voltage greater than an internal V FB reference voltage is applied
to this pin. The V FB reference voltage is internally set to 1.70 V.
LinkZero-AX goes into auto-restart mode when the FEEDBACK
pin voltage has come down to 0.9 V.
SOURCE (S) Pin:
This pin is the power MOSFET source connection. It is also the
ground reference for the BYPASS and FEEDBACK pins.
