Absolute Maximum Ratings

Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. 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.

Because of the IR2152’s application specificity toward off-line supply systems, this IC contains a zener clamp

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.
