Pin Function
Voltage Regulator Output. The V CC pin supplies the power to the internal circuitry. The VCC in the output
of a linear regulator which is powered from VIN. A 1μF ceramic capacitor is recommended for bypassing
and should be placed as close as possible to the VCC and AGND pins. Do not connect to an external
load.
Current-Sense Input. The CS pin provides the high-side current sense to set the LED current with an
external sense resistor.
Input Power Supply. VIN is the input supply pin to the internal circuitry and the positive input to the
current sense comparator. Due to the high frequency switching noise, a 10μF ceramic capacitor is
recommended to be placed as close as possible to VIN and the power ground (PGND) pin for
bypassing. Please refer to layout recommendations.
Ground pin for analog circuitry. Internal signal ground for all low power sections.
Enable Input. The EN pin provides a logic level control of the output and the voltage has to be 2.0V or
higher to enable the current regulator. The output stage is gated by the DIM pin. When the EN pin is
pulled low, the regulator goes to off state and the supply current of the device is greatly reduced (below
1μA). In the off state, during this period the output drive is placed in a "tri-stated" condition, where
MOSFET is in an “off” or non-conducting state. Do not drive the EN pin above the supply voltage.
PWM Dimming Input. The DIM pin provides the control for brightness of the LED. A PWM input can be
used to control the brightness of LED. DIM high enables the output and its voltage has to be at least
2.0V or higher. DIM low disables the output, regardless of EN “high” state.
Power Ground Pin for Power FET. Power Ground (PGND) is for the high-current switching with
hysteretic mode. The current loop for the power ground should be as small as possible and separate
from the Analog ground (AGND) loop. Refer to the layout considerations for more details.
Gate-Drive Output. Connect to the gate of an external N-channel MOSFET. The drain of the external
MOSFET connects directly to the inductor and provides the switching current necessary to operate in
hysteretic mode. Due to the high frequency switching and high voltage associated with this pin, the
switch node should be routed away from sensitive nodes.
