6.0 This IC's package is POWER-SSOP, so
(W) improving the board on which the IC is mounted
5.0
4.0W using H-type board
enables a large power dissipation without a heat
sink.
3.0W using I-type board
For example, using an 1 layer glass epoxy resin
board, the IC's power dissipation is 2.7W at
4.0 least. And it comes to 4.0W by using an improved
2.7W using J-type board
2 layer board.
The information of the H, I, J type board is shown
3.0 in the board information.
