ILD8150 80 V high side buck LED driver IC with hybrid dimming

Application circuit

3 Application circuit
This section provides more information about the reference design available. The board is configurable to have
an output current in the range 250 mA to 1500 mA, with current adjustment by jumpers X9 A, B and C, as shown
in Figure 16. The operating voltage range for the demo board can be from 8 V to 80 V. Jumper J3 activates open-
load protection and prevents output over-voltage to 60 V. The board is designed with two optional inductors –
through-hole for high power and SMD for low power. The schematics and PCB layout are shown in Figure 13
and Figure 15 respectively. The Bill of Materials (BOM) is in Appendix A.
