NAME
Description
VIN
This is the positive input supply for the IC switching regulator. A suitable input
bypass capacitor must be presented at this pin to minimize voltage transients
and to supply the switching currents needed by the regulator.
SW
Internal switch. The voltage at this pin switches between (+Vcc – Vsat) and
approximately – 0.5V, with a duty cycle of approximately Vout / Vcc. To
minimize coupling to sensitive circuitry, the PC board copper area connected
to this pin should be minimized.
FB
Sense the regulated output voltage to complete the feedback loop.
EN
Allows the switching regulator circuit to be shutdown using logic level signals
thus dropping the total input supply current to approximately 100uA. 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 Vcc) shuts the
regulator down. If this shutdown feature is not needed, the EN pin can be
wired to the ground pin.
