PIN NAME FUNCTION
1, 2 V
DD
Power Supply. Bypass V
DD
to ground with a 1FF capacitor as close as possible to the device.
3 CLK
Clock Input. Connect CLK to GND to enable internal clocking. Apply a clock signal to CLK to enable exter-
nal clocking.
4 EN Enable Input. Drive EN low to enable the device. Drive EN high to disable the device.
5 ITH
Overcurrent Threshold Adjustment Input. Connect a resistor (R
LIM
) from ITH to GND to set the overcurrent
threshold for the ST1 and ST2 outputs. Do not exceed 10pF of capacitance to GND on ITH.
6 FAULT
Fault Open-Drain Output. The fault open-drain transistor turns on when there is either an overtemperature or
overcurrent condition.
7, 9 GND Ground
8 ST2 Transformer Drive Output 2
10 ST1 Transformer Drive Output 1
— EP
Exposed Pad. Internally connected to GND. Connect EP to a large ground plane to maximize thermal perfor-
mance; not intended as an electrical connection point.
