FUNCTION
1
OUT
2
FB
3
SHDN
4
REF
1.5V reference output that can source 100A. Bypass to ground with 0.1F.
5
V+
Positive power-supply input
6
CS
Noninverting input to the current-sense comparator. Typical trip level is 210mV (relative to V+).
7
EXT
The gate-drive output for an external P-channel power MOSFET. EXT swings from OUT to V+.
8
GND
Ground
The sense input for fixed-output operation (VFB = VREF). OUT is connected to the internal voltage divider,
and it is the negative supply input for the EXT driver.
Feedback input. When VFB = VREF, the output will be the factory preset value. For adjustable operation,
use an external voltage divider, as described in the Adjustable Output section.
Active-high shutdown input. With SHDN high, the part is in shutdown mode and the supply current is less
than 5A. Connect to GND for normal operation.
