Thermal Derating
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.
The information of the N, P type board is shown in attached.
