Designed for 3 x 600mA leds(*) wired in serial.
‘'Vin’‘ supply shall be a regulated 12V.
The led controller is dimmable with a PWM signal on the ‘'Dim’‘ input (PWM frequency shall be no less than 200Hz and no more than 50 KHz).
Bottom side is a ‘'Gnd’‘ copper plan used for heatsink report.
Bill of Materials :
- Controller = TPS92511 (Texas Instument).
- Inductor = LPS5030-683 (Coilcraft).
- Diode = SS16 (Vishay).
- Capacitors = 1µF / 100V / 1210.
- Resistor RFS = 20Ku (for 500 KHz switching frequency. /!\ Change of switching frequency impact the inductor).
- Resistor Riadj = 3.01Ku (for 500 mA current limitation , can be adjust up to 10Ku that is equal to a 150 mA current limitation).
(*) Possibility to drive more or less leds (just take care to adjust ‘'Vin’‘ that can start from 4.5V up to 65V, and don’t forget heatsink aspect).
