Pin Description

1

Power Input

Power supply for control logic and BJT drive.

2

FB/OTP

Analog Input

Multi-function pin. Used for OTP current derating configuration at the

beginning of start-up and to provide auxiliary voltage sense for primary

regulation during normal operation.

3

ASU

Output

Control signal for active start-up device (BJT or depletion mode NFET).

4

CS/PF

Analog Input

Multi-function pin. Used for PF configuration at the beginning of start-up and

to provide primary current sense for cycle-by-cycle peak current control and

limit during normal operation.

5

GND

Ground

Ground.

6

OUTPUT

Output

Base drive for BJT.
