6. Typical Application Circuit

fig5. LC5830K Application Circuit

The application circuit in fig5 shows a design for driving a 15 V LED string at 1.3 A (set by RSENSE ). The switching

frequency is 500 kHz, as set by R1. As for the COUT, a 0.68 μF ceramic capacitor is added across the LED string to

reduce the ripple current through the LEDs (as shown in figure 17B).

*Refer to “9.2 demonstration board circuit diagram” for the circuit diagram of the demonstration board.
