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%.

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.
