7 / 9 page UC3655 Preliminary CMOS IC UNISONICTECHNOLOGIESCO.,LTD 7 of 9 www.unisonic.com.tw QW-R502-280..a OPERATIONAL EXPLANATION CE / MODE Pin Function When a low level signal is input to the CE/MODE pin the operation of the UC3655 series will enter into the shut down mode. In this mode, the current consumption occurs only in the detector and is 0 μA (TYP.), with a state of high impedance at the Lx pin and VOUT pin. By inputting a high level signal to the CE/MODE pin the IC starts its operation. The input of the CE/MODE pin is a CMOS input and its sink current is 0 μA (TYP.).
