Function of External Components:
The recommended number of external components used with the NTE1388 is 4 pieces as follows:
D Feedback Capacitor from Pin5, CNF
D Pin7 to Pin10 Bootstrap Capaciter, CBS
D Output Capacitor from Pin10, COUT
D High Frequency Paracitic Oscillation Compensating Capacitor, CX
The fixed values of these components are:
= 100µF
CNF
= 100µF
CBS
COUT = 1000µF
= 0.15µF
