BOOST (Pin 1):
The BOOST pin is used to provide a drive
voltage, higher than the input voltage, to the internal
bipolar NPN power switch.
GND (Pin 2):
Tie the GND pin to a local ground plane below
the LT1933 and the circuit components. Return the feed-
back divider to this pin.
FB (Pin 3):
The LT1933 regulates its feedback pin to
1.245V. Connect the feedback resistor divider tap to this
pin. Set the output voltage according to V
OUT
= 1.245V
(1 + R1/R2). A good value for R2 is 10k.
SHDN (Pin 4):
The SHDN pin is used to put the LT1933 in
shutdown mode. Tie to ground to shut down the LT1933.
Tie to 2.3V or more for normal operation. If the shutdown
feature is not used, tie this pin to the V
IN
pin. SHDN also
provides a soft-start function; see the Applications Infor-
mation section.
V
IN
(Pin 5):
The V
IN
pin supplies current to the LT1933’s
internal regulator and to the internal power switch. This
pin must be locally bypassed.
SW (Pin 6):
The SW pin is the output of the internal power
switch. Connect this pin to the inductor, catch diode and
boost capacitor.
