µ PC1933
3.5 Maximum Duty Limit
µ PC1933 is switched internally between Soft Start and Timer Latch. For this reason, the DTC voltage is fixed internally,
and the maximum duty is limited to 85%.
3.6 Notes on Actual Pattern Wiring
When actually carrying out the pattern wiring, it is necessary to separate control-related grounds and power-related
grounds, and make sure that they do not share impedances as far as possible. In addition, make sure the high-frequency
impedance is lowered using capacitors and other components to prevent noise input to the VREF pin.
