ILD8150EXUMA1

ILD8150EXUMA1 is a LED driver IC for high-power LED with hybrid dimming down to 0.5%. It is DC/DC converter IC for LED applications to drive high-power LED. For applications operating close to SELV limits it provides a high safety voltage margin. The buck LED driver IC is tailored for LED in general lighting applications with average currents up to 1.5A using a high-side integrated switch. A complete set of features and protections provide a well fit for professional LED lighting solutions. The hysteretic current control provides an extremely fast regulation and stable LED current combined with good EMI performance. The efficiency of the LED driver is remarkable high due to the low RON of the internal switch. Hybrid dimming is an Infineon unique one-pin dimming method that combines analogue dimming and PWM dimming of the LED current in one hybrid dimming curve. Potential application includes electronic control gear (ECG) for LED luminaries.
