Control amplifier
• The voltage integrated in the charge pump is input to the control amplifier.
• The control amplifier circuit has an offset of 0.45 V (typ.). If the CP pin voltage exceeds the offset value,
• The PWM duty ratio indicates the value at the peak of the modulation waveform. A duty ratio of 100%
The input is placed in high-impedance state because it is a P-ch gate.
the energization signal outputs become active. It incorporates a clamp circuit that saturates the PWM
duty ratio for the energization signal outputs when the CP pin voltage becomes 2.7 V (typ.).
indicates that the peak value coincides with the peak of the triangular wave.
