Infineon REFTWILD8150E60V1ATOBO1, ILD8150E Tunable White Evaluation Board LED Driver Evaluation Board for ILD8150E for / 2286711

The Infineon tunable white reference board consists of 80V DC-DC buck LED driver IC ILD8150E and monolithic integrated fixed NPN type voltage regulator IFX1117ME V33. The LED Driver IC consists of two identical channels and one auxiliary 3.3 V supply. To achieve higher light quality it employs output electrolytic capacitors to further smooth output current. An electrolytic capacitor and an LDO are used to provide a smooth supply of 3.3 V and up to 60 mA for the dimming control circuit. The two channels operate at frequencies of up to 500 kHz, the output current can be changed in the range of 250 to 1500 mA.Analog dimming down to 12.5 % and PWM dimming from 12.5 % to 0.5 % Current precision ±3 % Soft-start, UVLO, current limitation, low-power shutdown Deep dimming performance without flicker and noise via an innovative one-pin hybrid method High current precision leads to high light quality, also in color accuracy Fast, stable and efficient regulation without audible noise Easy implementation of tunable white designs
