Output pin for motor drive : connect a low impedance capacitor with a recommended capacit-
ance of 470
μ
F / 35V.
Test pin ; use this internally connected pin in OPEN mode.
Output voltage control pin ; PWM signal or DC signal is inputted. The output voltage can be
changed either by changing the duty of PWM signal or by changing the DC voltage value.
Ground pin
Test pin ; use this internally connected pin in OPEN mode.
Input pin ; connect a low impedance capacitor with a recommended capacitance of
100
