ILD8150/ILD8150E
LED driver IC for high power LEDs with hybrid dimming down to 0.5%
Description
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 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 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 efficiency.
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 soft-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 off 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.

Functional description
This chapter provides a summary of the integrated functions and features, and describes the relationships
between them. The parameters and equations are based on typical values at TA = 25 °C.
3.1
Buck controller features
3.1.1
Output current regulation
The hysteretic control allows fast and always stable output current and guarantees an intrinsic cycle-by-cycle
over-current protection.
The pin CS feeds back the voltage level on the current sense resistor RCS to the hysteretic controller.
The hysteretic controller implements two voltage thresholds VCSH and VCSL. When the CS voltage crosses
above the VCSH threshold the internal switch turns-off. When the CS voltage crosses below the VCSL the
internal switch turns-on. The thresholds VCSH and VCSL determine the output current peak-to-peak ripple
I OUT, RIPPLE = V CSH − V CSL /RCS . The target LEDs current is the undimmed average current determined by the
formula I LED, AVG = V CS, AVG /RCS with V CS, AVG = V CSH + V CSL /2 . The continuous-conduction-mode (CCM)
timings are tON = I OUT, RIPPLE ∙ L / V V IN − V OUT and tOFF = I OUT, RIPPLE ∙ L /V OUT .
Figure 4 show the CCM output current waveform.

3.1.2
Dimming
tOFF
In analog dimming the output current is proportional to the internal CS reference voltage and the output
current varies analogically between 100% and 12.5% of the target output current. Hybrid dimming applies
below 12.5% of the target output current so that the output current is stable at 12.5% and amplitude
modulated. The modulation signal has a frequency of typically 3.4 kHz to satisfy the IEEE1789-2015
recommendation for no observable flicker in light.
Figure 5 shows the mapping between the input PWM duty cycle and the output current as a ratio of the target
output current. Figure 8 shows the detail of dim-to-off.

The ILD8150 turns the output stage respectively off when the PWM dimming input signal duty cycle is less than

levels create a hysteresis that avoids unstable states at the on/off boundary.

The ILD8150 evaluates the PWM dimming input signal duty cycle DPWM_IN at the DIM pin. In analog dimming
the duty cycle maps to a proportional CS reference voltage. In hybrid dimming the duty cycle maps to a hybrid
dimming duty cycle using the hybrid dimming curve. The hybrid dimming frequency is fixed and does not relate
to the input PWM frequency.

Digital soft-start
Soft-start is a feature that smooths output current transients during start-up.
Output current smoothing is digitally managed by the IC and applies in case of abrupt dimming changes. When
the IC goes to dim-to-off the output current smoothing applies resulting in a soft-stop behavior. Benefits are the
avoidance of under shoots or over shoots at primary side reflecting in a stable power regulation and reduction
of components stress.
Digital soft-start uses of the PWM dimming signal. The PWM duty cycle sets the target dimming level and the
PWM frequency sets the speed to reach that level. To lower PWM frequencies correspond a slower soft-start,
to higher PWM frequencies correspond a faster soft-start. The output current ramps up to the target value in a
determined soft start time tSS. tSS is defined as the time to reach the desired dimming level from a change in
the PWM dimming signal. The number of steps of the soft-start ramp may vary depending on the actual and the
target dimming level.

Output current smoothing does not affect the output current for small variations of the dimming
signal e.g. to create light fading effects.
Low power mode
If the shut-down signal (SD neg.) is driven low for more than tSD_LO the low power mode is active. If the
shut-down signal is held high for more than tSD_HI the IC resumes from low power mode. –ISD,HPU dynamic
current is needed to turn the IC into low power mode, then the current changes into static –ISD,LPU. DIM pin
needs to be driven externally with at least VDIM,SD voltage during low power mode.

Over-temperature protection
The over-temperature protection turns off the output stage when the junction temperature exceeds the
temperature threshold TOT,OFF. When the junction temperature falls below the temperature threshold TOT,ON
the output stage turns on again.
In case of over-temperature the IC stops switching and waits for the over-temperature condition to disappear.

Under-voltage protection
The gate driver implements an under-voltage lock-out (UVLO) protection at high-side that switches-off the gate
driver in case of BOOT under voltage (e.g. due to wrong bootstrap capacitor selection or incorrect system
dimensioning).
In case of gate driver UVLO, the switch activity is interrupted in order to reload the bootstrap capacitor charge.

Remarks
Latch-up according to JEDEC JESD78D, TA= 85°C.
Two different classes of ESD protection elements are implemented within ILD8150/ILD8150E: 1. ESD
protection at pin VS will be triggered if the voltage at pin VS rises by more than 5 V with a slew rate
of more than 5 V/µs. This condition is met during an ESD event, but might also occur if the LED driver
gets hotplugged into a power supply and the VS blocking capacitor has a too small capacitance. ESD
protection will remain triggered as long as the slewrate condition is met. If the ESD protection gets
triggered while VS is supplied the IC might be damaged. 2. ESD protection at all other pins is triggered
once the connected voltage signal exceeds a threshold higher than the maximum voltage rating specified
for each pin. No preventions regarding slew rate control need to be taken for these pins..
ESD-HBM according to JEDEC JS-001.
ESD-CDM according to JEDEC JS-002.
The voltage difference between BOOT and SW pins must never exceed 9 V.
