KAC-X810D/PS810D CIRCUIT DESCRIPTION 1. PWM Signal Waveform Generation A and B are sent to the comparator so as to generate the The waveform of C is divided into upper and lower gate PWM waveform of C. (A clock of 50% in duty ratio is waveforms.
KAC-X810D/PS810D CIRCUIT DESCRIPTION 2. D-AMP Block The voltages at the upper and lower gates are current- converted using Q14 and Q16 to Q19. The converted current is returned to a voltage using R167 and R168 to drive MOSFET by Q30 to Q33 and Q39 to Q42 (push-pull operation).
KAC-X810D/PS810D CIRCUIT DESCRIPTION 3. Overcurrent Detector Circuit The signal level detected in A and B appears in C, and the signal is current-converted using Q54 and R227. The converted current is voltage-converted using R233, and the output signal of IC12 is set "high" when the voltage becomes more than +7.5 V.
