PIN FUNCTION
VIN is the supply pin for the driver. A small 1 μF
ceramic bypass capacitor is required between the VIN
pin and ground near the device. The operating input
voltage range is from 2.7 V to 5.5 V. If the input
supply
voltage
falls
below
the
under-voltage
threshold, switch is disabled, and the device enters
shutdown mode.
HVB is the internal high voltage reference point.
Connect a 4700 µF capacitor between this point and
VOUT.
EN/PWM is the Enable/Smart OneWire
™ inteface
and PWM control logic input. Guaranteed levels of
logic high and logic low are set at 1.4 V and 0.4 V
respectively. When EN/PWM is initially taken high,
the device becomes enabled and wait for the first
pulse that determines mode, at which device will
operate. If first pulse is equal tSETUP1, LED current sets
to
factory
programmed
value
and
every
next
incoming pulse will be recognized as PWM signal. If
first pulse is equal tSETUP2,
device enters Smart
OneWire
™ interface mode and wait for command.
Every next of 16 incoming pulses will be recognized
as command. If device is not able to recognize
command due error in transmition, it enters shutdown
mode after 10 ms. To place the device into shutdown
mode, the EN/PWM pin must be held low for more
than 10 ms.
VOUT is the driver’ output that is connected to the LED
anode. A ceramic bypass capacitor is required
between the VOUT pin and ground near the device.
GND is the ground reference for the analog circuits.
The pin must be connected to the ground plane on
the PCB. Avoid high currents flowing trough traces
connecting this pin with EN/PWM signal source.
PGND is the current return for high current circuits.
The pin must be connected to the ground plane on
the PCB. Connect GND and PGND as close to the
driver as possible.
LEDS is the Current Sense pin that provides internal
regulated current sink for LED string. Connect LED
string cathode to this pin. This pin enter high-
impedance zero current state whenever the device is
in shutdown mode.
PAD is the exposed pad underneath the package.
For best thermal performance, the pad should be
soldered to the PCB and connected to the ground
plane
