Output Measurement
A sample of input LED signals and various output waveforms are captured and shown in Figure 6. The default setup
connection is adopted, but with Q1a and Q1b switchers mounted. The switchers have a gate capacitance equivalent to
10 nF.

Note: Both IN1+ and IN2+ are set at 49% duty ratio.
Figure 7 shows the turn-off gate signal of Q1a and the turn-on gate signal of Q1b:
