MASTER MODE USING
EXTERNAL SYNC SIGNAL
(SYNC ONLY)
MASTER MODE USING
EXTERNAL SYNC SIGNAL
(SYNC AND DIMMING)
SLAVE MODE
CNTL
An analog voltage on CNTL
sets the brightness.
An analog voltage on CNTL
sets the brightness.
CNTL control is disabled.
The external signal controls
the brightness. Connect
CNTL to an analog voltage
in case the external sync
signal is lost.
Connect CNTL to V
CC
.
Brightness is controlled
by the master.
SEL
Connect SEL to GND.
Connect SEL to GND.
Switching frequency is
controlled by the external
sync signal. Connect a
resistor to GND in case the
external sync signal is lost.
DPWM frequency is
determined by the external
sync signal. Connect a
resistor to GND in case the
external sync signal is lost.
Connect SEL to V
CC
.
Switching frequency is
controlled by the external
sync signal. Connect a
resistor to GND in case the
external sync signal is lost.
DPWM frequency is
determined by the external
sync signal. Connect a
resistor to GND in case the
external sync signal is lost.
Don’t care.
HF
Connect a resistor to GND to
set the switching frequency.
Connect to the PSCK
pin of its master
controller.
LF
Connect a resistor to GND to
set DPWM frequency.
Connect to the DPWM
pin of its master
controller.
HFCK
Connect to the HFCK pin of
its slave controller.
Connect to the HFCK pin of its
slave controller.
Connect to the HFCK pin of
its slave controller.
Connect to the HFCK
pin of its master
controller. Connect a
1M
Ω
resistor to GND.
Connect to the LFCK
pin of its master
controller. Connect a
1M
Ω
resistor to GND.
LFCK
Connect to the LFCK pin of
its slave controller.
Connect to the LFCK pin of its
slave controller.
Connect to the LFCK pin of
its slave controller.
HSYNC
Not used. Connect to GND.
Connect to a high-frequency
external signal to sync the
switching frequency.
Connect to a high-
frequency external signal to
sync the switching
frequency.
Not used.
Connect to GND.
LSYNC
Not used. Connect to GND.
Connect a low-frequency
external signal to sync the
digital PWM frequency.
Connect a low-frequency
external signal to sync the
digital PWM frequency. The
duty cycle of the external
signal determines the
brightness.
Not used.
Connect to GND.
PSCK
Connect to the HF pin of its
slave controller.
Connect to the HF pin of its
slave controller.
Connect to the HF pin of its
slave controller.
Connect to the HF pin
of its slave controller.
DPWM
Connect to the LF pin of its
slave controller.
