Fig. 36 Gate circuit
When gate resistance differs between ON and OFF as shown
in Figure 36, the loss is given by:
(
... (17)
Example:
When Vcc = 18V, Qg = 80nC, fsw = 100kHz, and Rg = 10
, the
typical IC loss is given by:
Pdr = 1

(3) Total loss
The total loss (Pd) of the IC is the sum of the control circuit loss
(Pop) and the output circuit loss (Pdr) calculated previously:
Pd = Pop + Pdr .............................................................. (18)
Example:
The standard IC loss under the conditions used in (1) and (2)
above are:
Pd = Pop + Pdr = 34.2mW + 72.8mW = 107mW
Pdr = 1
