All voltage param- eters are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air conditions. Recommended Operating Conditions The Input/Output logic timing diagram is shown in Figure 1. For proper operation the device should be used within the recommended conditions. The VS offset rating is tested with all supplies biased at 15V differential. V °C/W W mA V structure between the chip VCC and COM which has a nominal breakdown voltage of 15.6V. Therefore, the IC supply voltage is normally derived by forcing current into the supply lead (typically by means of a high value resistor connected between the chip VCC and the rectified line voltage and a local decoupling capacitor from VCC to COM) and allowing the internal zener clamp circuit to determine the nominal supply voltage. There- fore, this circuit should not be driven by a DC, low impedance power source of greater than VCLAMP. Note 1: Because of the IR2152’s application specificity toward off-line supply systems, this IC contains a zener clamp Next Data Sheet Index Previous Datasheet To Order |
