Description

The ILD8150 is a 80 V DC/DC converter IC for LED applications to drive high-power LEDs. For applications

operating close to SELV limits it provides a high safety voltage margin. The buck LED driver IC is tailored for

LEDs in general lighting applications with average currents up to 1.5 A using a high-side integrated switch. A

complete set of features and protections provide a well fit for professional LED lighting solutions.

Performance and innovation

The hysteretic current control provides an extremely fast regulation and stable LED current combined with good

EMI performance. The eiciency of the LED driver is remarkable high due to the low R

of the internal switch.

Hybrid dimming is an Infineon unique one-pin dimming method that combines analog dimming and PWM

dimming of the LEDs current in one hybrid dimming curve.

A PWM input signal between 250 Hz and 20 kHz controls dimming of the LEDs current in analog mode from 100

percent to 12.5 percent and 12.5 percent to 0.5 percent in hybrid mode with flicker-free modulation frequency

of 3.4 kHz. The digital PWM dimming detection with high resolution makes it the perfect match for

microcontroller and high quality dimming applications.

The IC supply is directly driven from the primary stage and the low-power shut down contributes to a very high

stand-by system eiciency.

High output current accuracy from device to device under all loads and input voltages conditions makes it

perfect for tunable white and flat panel designs where current must be identical string to string.

Protection

A wide range of operating supply voltage from 8 V to 80 V DC enables a wide use in many applications and

provides a good margin when bus voltage exceeds shortly the SELV limits.

The so-start function protects the primary stage from abrupt current request.

The over temperature protection is triggered when the junction temperature exceeds the temperature

threshold turning o the output stage. The output stage turns on again when the junction temperature falls

below the temperature threshold.

Under voltage lock-out protects the bootstrap voltage and the hysteretic design ensures cycle-by-cycle current

limitation.
