10 Application information

Current Setting

If the application circuit is same as below

SET1

SET2

SET3

SET4

SET5

SET6

TAP1

TAP2

TAP3

TAP4

TAP5

TAP6

Rset1

Rset2

Rset3

The current setting will be

I_TAP5-6= (1.2V ÷ (R_SET3))

I_TAP3-4= (1.1V ÷ (R_SET3+ R_SET2))

I_TAP1-2= (1.1V ÷ (R_SET3+ R_SET2+ R_SET1))

R_SET3= (1.2V ÷ I_TAP5-6

)

R_SET2= (1.1V ÷ I_TAP3-4) – R_SET3

R_SET1= (1.1V ÷ I_TAP1-2) – R_SET3– R_SET2

The MG39132 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 132 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 9°C0 (Celsius degree). For ETSSOP16

package, maintain the power dissipation below 1.5W.
