50/100-W Flyback reference design for audio applications

This reference design implements a dual-output flyback using the cost effective LM5021 AC-DC Current-Mode PWM Controller. Universal line input is converted to both 24-V and 6-V outputs. The TLV1117 Fixed LDO Voltage Regulator converts the 6-V output to 3.3 V and can handle 0.2 A of current. The (...)

Junction temperature vs. PCB copper coverage area
These are estimated power dissipation and thermal results.
Care must be taken to ensure that device junction temperature
does not exeed the maximum ratings as indicated in the datasheet.

This calculator uses the PCB copper area to estimate the device junction temperature. See notes on usage and calculation method.
