PIN FUNCTIONS RUN (B4):
Run Control Input Pin. Enable regulator opera-
PGOOD (B5):
Output Power Good Pin with Open-Drain tion by tying the specific RUN pin above 1.25V. Tying it Logic. PGOOD is pulled to ground when the voltage on below 1.1V shuts down the specific regulator channel. the FB pin is not within ±8% of the internal 0.6V reference.
T + – SENSE (A6):
Temperature Monitor Pin. An internal diode
TSENSE (A7):
Low Side of the Internal Temperature Monitor. connected PNP transistor is placed between T + SENSE and
SW (B7):
Switching node of each channel that is used T – SENSE pins. See the Applications Information section. for testing purposes. Also an R-C snubber network can
GND (B2, B6, C3-C7, D5-D7, E5-E7, F5-F7, G6-G7):
be applied to reduce or eliminate switch node ringing, or Power Ground Pins for Both Input and Output Returns. otherwise leave floating.
