PIN DESCRIPTION

Pin Name Function

CTRL Analog dimming control and shutdown pin.

GND Ground reference.

RSET RSET pin. A resistor connected between the pin and ground sets the average LED current.

SW Interface to the inductor.

VBAT Supply voltage for the device.

PIN FUNCTION

VBAT is the supply input to the device. Typical current

conduction into this pin is less than 1mA and voltage

transients of up to 40V can be applied. To ensure

accurate LED current regulation, the VBAT voltage

should be 3V higher than the total forward voltage of

the LED string. A bypass capacitor of 4.7µF or larger

is recommended between VBAT and GND.

GND is the ground reference pin. This pin should be

connected directly to the ground plane on the PCB.

SW pin is the drain terminal of the internal low

resistance high-voltage power MOSFET. The inductor

and the Schottky diode anode should be connected to

the SW pin. Voltages of up to 40V can be safely

handled on the SW pin. Traces going to the SW pin

should be as short as possible with minimum loop

area. The device can handle safely “open-LED” or

“shorted-LED” fault conditions.

CTRL is the analog dimming and control input. An

internal pull-down current of 20µA allows the LEDs to

shutdown if CTRL is left floating. Voltages of up to

40V can be safely handled by the CTRL input pin.

RSET pin is regulated at 1.2V. A resistor connected

between the RSET pin and ground sets the LED full-

scale brightness current. The external resistance

value and the CTRL pin voltage determine the LED

current during analog dimming.

When the CTRL voltage is less than 0.9V (typ), the

LEDs will shutdown to zero current. When the CTRL

voltage is greater than about 2.6V, full scale

brightness is applied to the LED output. At voltages of

less than around 2.6V, the LED current is

progressively dimmed until shutdown.

For lamp replacement applications, or applications

where operation in dropout mode is expected, it is

recommended that the CTRL pin voltage be derived

from the LED cathode terminal.
