The test bench shows the behavior of TLD5045EJ while powering a high-power LED in
PWM mode. The dimming is generated by the internal PWM engine using external RC
network. The PWM engine can be disabled via J1 jumper (one-click on symbol to toggle position).
The output current is set to a peak value of 580 mA via RSET external resistor. Switching
frequency can also be adjusted via external RC network.
