(DD/TSSOP)
V OUT1 (Pin 1/Pin 3): Output of Converter 1. This pin is
connected to the cathode of the internal Schottky diode.
Connect an output capacitor from this pin to ground.
SW1 (Pin 2/Pin 4): Switch Pin for Converter 1. Connect the
inductor at this pin.
V IN (Pin 3/Pin 5): Input Supply Pin. Must be locally
bypassed with a 1 μ F, X5R or X7R type ceramic capacitor.
SW2 (Pin 4/Pin 6): Switch Pin for Converter 2. Connect the
inductor at this pin.
V OUT2 (Pin 5/Pin 7): Output of Converter 2. This pin is
connected to the cathode of the internal Schottky diode.
Connect an output capacitor from this pin to ground.
FB2 (Pin 6/Pin 10): Feedback Pin for Converter 2. The
nominal voltage at this pin is 200mV. Connect cathode of
the lowest LED and the feedback resisitor at this pin. The
LED current can be programmed by :
I LED2 ≈ (200mV/R FB2 ), when V CTRL2 > 1.6V
I LED2 ≈ (V CTRL2 /5 ? R FB2 ), when V CTRL2 < 1V
R T (Pin 8/Pin 12): Timing Resistor to Program the Switch-
ing Frequency. The switching frequency can be pro-
grammed from 200KHz to 2MHz.
CTRL1 (Pin 9/Pin 14): Dimming and Shutdown Pin for
Converter 1. Connect this pin to ground to disable the
converter. As the pin voltage is ramped from 0V to 1.6V,
the LED current ramps from 0 to I LED1 (= 200mV/R FB1 ).
Any voltage above 1.6V does not affect the LED current.
FB1 (Pin 10/Pin 15): Feedback Pin for Converter 1. The
nominal voltage at this pin is 200mV. Connect cathode of
the lowest LED and the feedback resistor at this pin. The
LED current can be programmed by :
I LED1 ≈ (200mV/R FB1 ), when V CTRL1 > 1.6V
I LED1 ≈ (V CTRL1 /5 ? R FB1 ), when V CTRL1 < 1V
Exposed Pad (Pin 11/Pin 17): The Exposed Pad must be
soldered to the PCB system ground.
GND (NA/Pins 1, 8, 9, 16): These pins are internally fused
to the Exposed Pad (TSSOP package only). Connect these
GND pins and the Exposed Pad to the PCB system ground.
CTRL2 (Pin 7/Pin 11): Dimming and Shutdown Pin for
Converter 2. Connect this pin to ground to disable the
converter. As the pin voltage is ramped from 0V to 1.6V,
the LED current ramps from 0 to I LED2 (= 200mV/R FB2 ).
Any voltage above 1.6V does not affect the LED current.
