The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7 4-layer board. 50/60Hz AC RMS Voltage ............. 85V to 305V VB ,VD .............................................. 8V to 30V Operating Junction Temp.

Figure 6 shows how it is implemented. More MP100 can be paralleled in the same way to get the output power need. Another way to get more output power is using an external MOSFET to charge the capacitor connected between VD and GND. Figure 7 shows an example. To prevent the thermal damage of external MOS when VD is shorted to GND directly, PTC (Positive Temperature Coefficient) is used which should be placed as close as to the external MOS to detect the temperature. When the temperature of external MOS reaches certain value, the resistor of PTC will increase sharply to pull down the gate voltage and shut down the external MOS. To guarantee its normal start up and steady state operation, R3/R2 should be more than 4.5. At the same time, R3/R2 should not be too high to get better thermal protection; generally it should be MP100 Rev. 1.04 1/23/2014 EMI An appropriate X-capacitor should be connected between the input ports to guarantee the circuit can meet EMI requirements.

With 750V switch integrated, MP100 can pass 1kV surge test with an appropriate MOV connected between the line input ports. PCB Layout Guide PCB layout is very important to achieve good regulation, ripple rejection, transient response and thermal performance. It is highly recommended to duplicate EVB layout for optimum performance.
