[5] About logic of PWM block
The logic for channel 1 and channel 2 of this IC is reversed. Thereby an input current flatness is realized. At the
same time, noise can be suppressed to a lower level by staggering the turn on timing.
The PWM1 block turns on the output transistor during the period when the triangular wave of the OSC terminal
(pin 1) is lower than both of the FB1 (pin 4) terminal voltage and the DT1 (pin 5) terminal voltage.
The PWM2 block turns on the output transistor during the period when the triangular wave of the OSC terminal
(pin 1) is higher than both of the FB2 (pin 13) terminal voltage and the DT2 (pin 12) terminal voltage.
