Function

Control amplifier frequency correction.

Inserting a capacitor (about 5600pF) between this

pin and ground will stop closed loop oscillation in

the current control system. The output current

response characteristics will be degraded if the

capacitor is too large.

Equivalent circuit

22

VREG Stabilized power supply (6.3V)

Insert a capacitor (about 0.1μF) between this pin

and ground for stabilization.

SUB pin.

Connect this pin to ground.

25

RF

Output current detection.

Insert low-valued resistors (Rf) between these

pins and ground. The output current will be limited

to the value set by the equation IOUT = VL/Rf.
