ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute
voltages referenced to COM, all currents are defined positive into any lead. The Thermal Resistance and Power Dissipation ratings are
measured under board mounted and still air conditions.

Note 1: Because the MPIC2151 is designed specifically for off–line supply systems, this IC contains a zener clamp structure between the chip
VCC and COM which has a nominal breakdown voltage of 15.6 V. 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 decoup-
ling capacitor from VCC to COM) and allowing the internal zener clamp circuit to determine the nominal supply voltage. Therefore, this circuit
should not be driven by a DC, low impedance power source of greater than VCLAMP.
