10 Application information

Current Setting

If the application circuit is same as below

The current setting will be

The MG39134 can sustain an input voltage level as high as 500V. But users should care the heat dissipation

issue for their applications. For large wattage application, the 134 will consumes 2W~3W power. The IC

’s heat-

sink should be firmly attached to the substrate. Aluminum or Ceramic PCB is recommended.

Package Thermal Resistance

The thermal resistance is around 66

°C /W, junction to ambient (no air flow)

Note: Rule of thumb, it is suggested that the IC surface temperature is maintained below 90

°C (Celsius degree). For ETSSOP16

package, maintain the power dissipation below 1.5W.
