Pin Function
Pin Name
Pin#
Function
VIN
1
This is the positive input supply for the IC switching regulator. A suitable input bypass capacitor
must be present at this pin to minimize voltage transients and to supply the switching current
needed by regulator.
Output
2
Internal switch. The voltage at this pin switches between (+VIN - VSAT) and approximately -0.5V,
with a duty cycle of approximately VOUT/VIN. To minimize coupling to sensitive circuitry, the PC
board copper area connected to this pin should be keep to a minimum.
Feedback(FB)
3
Senses the regulated output voltage to complete the feedback loop
.
ON/OFF(SD)
4
Allows the switching regulator circuit to be shutdown using logic level signals. Thus drop the total
input supply current to approximately 150 A. Pulling this pin below a threshold voltage of
approximately 1.3V turns the regulator on, and pulling this pin above 1.3V (up to a maximum of
18V) shuts the regulator down. If this shutdown feature is not needed, ON/OFF pin can be wired to
the ground pin.
