Connecting Unused Error Amplifiers
When the unused circuit of the three control circuits provided internally is error amplifier E/A
2
, connect the circuit in such
a way as to make sure that the output of the error amplifier is low. When the unused circuit is error amplifier E/A
3
, connect
the circuit in such a way as to make sure that the output of the error amplifier is high. In the case of error amplifier E/A
1
,
the Dead Time Control pin is fixed internally, so be sure to always use this amplifier.
Figure 3-2 shows examples of how to connect unused error amplifiers.
