11 C-HICCUP

It is capacitor connection pin for setting re-startup cycle in

HICCUP mode．

If connect it to GND pin, then latch-off when over current.

12 SS

Capacitor connection pin for soft start.

About 2μA current charges the soft start capacitor.

14 COMP

NC pin.

Error Amplifier Output Pin．

The phase compensation network is connected between GND

pin and COMP pin．

Thanks to current-mode control, COMP pin voltage would tell

you the output current amplitude. COMP pin is connected

internally to an int.comparator which comparators with 0.9V

reference. If COMP pin voltage is larger than.

0.9V, IC operates in “continuous mode”. If COMP pin voltage is

smaller than 0.9V, IC operates in “discontinuous mode (low

consumption mode)”.
