VID
Index pulse output and index delay pulse output
power supply pin.
For applications when VCC equals 5V,
VCC=VID=5V.

VCC
Total power supply voltage pin except for VID.
Voltage must be stable and free of ripple and noise
interference.
34
Rf
Output current detection pin.
By installing an Rf resistor between this pin and
VCC, output current is detected as voltage. Voltage
detection at this pin activates the current limiter.
