NCL30076
www.onsemi.com
The NCL30076 is a DC−DC buck controller for wide dimming
range down to 1% by analog dimming control to relieve audible noise
and flicker in PWM dimming. ON Semiconductor’s proprietary LED
current calculation technique driven by zero input offset amplifiers
performs precise constant current in the whole analog dimming range.
Multi−mode operation provides high efficiency with minimized
switching loss by QR at heavy load and deep analog dimming by DCM
at light load.

PWM dimming control is also provided in case that constant LED
color temperature is required. The NCL30076 has several protections
such as LED short protection, over current protection, thermal
shutdown and VDD over voltage protection for robust system
reliability.

APPLICATION INFORMATION
General
Therefore, NCL30076 supports low CC tolerance less
NCL30076 provides wide analog dimming down to 1%
than 2% at full load and 20% at 1% load in the system
variation.
with accurate CC regulation. According to buck inductor,
input voltage and output voltage, deep dimming down to
0.1~0.2% load can be achieved. Thanks to
ON Semiconductor’s proprietary LED current calculation
technique, NCL30076 is able to sense the current of LED
load connected at input voltage node with no upper limit of
the input voltage with high design flexibility and system
reliability. LED current sensed by internal zero input offset
amplifiers performs accurate CC regulation in the whole
analog dimming range. Therefore, CC tolerance is tightly
controlled within 2% at 100% load and 20% at 1% load.
Soft start
At startup, an internal soft start block gradually reduces
T
OFF
time from maximum T
limit so that LED current is
OFF
settled smoothly without overshoot current and unexpected
flash.
Standby Mode
When V
is lower than a standby threshold voltage for
DIM
10 ms, standby mode is triggered with LED turn−off and IC
current consumption is minimized.
Wide Analog Dimming
Auto Restart (AR) at Protection
Wide analog dimming range is obtained by transitioning
multi−mode operation between QR and DCM according to
the dimming condition. At full load condition, QR with
valley switching minimizes switching loss for high system
efficiency and DCM is activated at light load condition to
perform deep analog dimming. Internal LED current
calculator and a digital compensator provide dimming
linearity over the entire dimming range.
Once protection is triggered, IC operation stops for
1 second and begins soft start operation after the auto restart
time delay.
VDD Over Voltage Protection (OVP)
When VDD is higher than V
voltage protection is triggered.
threshold, over
DD (OVP)
Short LED Protection (SLP)
PWM Dimming
When LED is short circuited, the buck stage operates at
minimum switching frequency, so the maximum turn−off
time control protects the freewheeling diode from thermal
stress.
Analog dimming has benefits for less audible noise and
flicker compared to PWM dimming. However, PWM
dimming method is generally required to keep the constant
LED color temperature in specific applications. NCL30076
supports PWM diming by simply providing PWM dimming
signal to DIM pin.
Over Current Protection (OCP)
When CSZCD voltage exceeds the over current threshold
voltage, switching is immediately shut down after leading
edge blanking time in the short circuit condition of the
inductor or the freewheeling diode.
Precise CC Regulation
CC regulation is very important especially in
programmable LED driver system to keep constant LED
current under system variation of LED load, inductor,
temperature, etc. NCL30076 applies zero input offset
amplifiers at LED current calculator and OTA. Those blocks
can implement precise LED current sensing and FB voltage
generation.
Thermal Shot Down (TSD)
When IC junction temperature is higher than 150°C, TSD
is triggered and released when the temperature is lower than
120°C.
