Descriptions

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)”.

Error amplifier reverse input pin．

ICs make its voltage keep 1.26V. Output voltage is divided by

external resistors and it across FB.
