SW (Pin 1): Boost Converter Switch Pin. Connect induc-
tor/diode here. Minimize trace area at this pin to keep EMI
down.
SWGND (Pin 2): Switch Ground. Tie directly to the local
ground plane and the GNDs at Pins 6 and 15.
V
IN1
(Pin 3): Boost Converter Input Supply Pin. Must be
locally bypassed.
SHDN2 (Pin 4): This is a multifunction shutdown pin that
provides GATE drive latchoff capability. A 15礎 current
source, that turns on when current limit is activated,
charges a capacitor placed in series with SHDN2 to GND
and performs a current limit time-out function. The pin is
also the input to a comparator referenced to V
REF
(1.21V).
When the pin pulls above V
REF
, the comparator latches the
gate drive to the external MOSFET off. The comparator
typically has 100mV of hysteresis and the SHDN2 pin can
be pulled low to reset the latchoff function. This pin
provides overvoltage protection or thermal shutdown
protection when driven from various resistor divider
schemes.
