Pin Functional Description  
SOURCE (S) Pin:  
This pin is the power MOSFET source connection. It is also the  
ground reference for the BYPASS and FEEDBACK pins.  
DRAIN (D) Pin:  
Power MOSFET drain connection. Provides internal operating current  
for both start-up and steady-state operation.  
BYPASS (BP/M) Pin:  
This pin has multiple functions:  
It is the connection point for an external bypass capacitor for the  
internally generated 5.0 V supply.  
P Package (DIP-8C)  
G Package (SMD-8C)  
D Package (SO-8C)  
It is a mode selector for the current limit value, depending on the  
value of the capacitance added. Use of a 0.1 μF capacitor results  
in the standard current limit value. Use of a 1 μF capacitor results  
in the current limit being reduced, allowing design with lowest cost  
surface mount buck chokes.  
It provides a shutdown function. When the current into the BYPASS  
pin exceeds IBPSD for a time equal to 2 to 3 cycles of the internal  
oscilator (fOSC), the device enters auto-restart. This can be used to  
provide an output overvoltage protection function with external  
circuitry.

FEEDBACK (FB) Pin:  
During normal operation, switching of the power MOSFET is con-  
trolled by the FEEDBACK pin. MOSFET switching is terminated when  
a current greater than IFB (49 μA) is delivered into this pin. Line  
overvoltage protection is detected when a current greater than IFBSD  
(670 μA) is delivered into this pin for 2 consecutive switching cycles.
