... M63028/029FP Thermal Derating 6.0 (W) 5.0 4.0 3.0 2.0 1.0 0 This IC's package is POWER-SSOP, so improving the board on which the IC is mounted enables a large power dissipation without a heat sink. For example, using an 1 layer glass epoxy resin board, the IC's power dissipation is 2.6W at least. And it comes to 3.6W by using an improved 2 layer board. ...
