1. Specifications
1.1 Package Pinout
1.3 Absolute Maximum Ratings
Electrical absolute maximum ratings are at 25ºC.
Absolute maximum ratings are stress ratings.
Stresses in excess of these ratings can cause
permanent damage to the device. Functional
operation of the device at conditions beyond those
indicated in the operational sections of this data sheet
is not implied.

Input voltage
LED Current Sense input. Internal current
sense threshold is set at V
external sense resistor sets the maximum LED
current.
Device Ground
External MOSFET gate driver output
Low-frequency PWM dimming control input with
internal pull-down resistor.
Regulated supply voltage output. Requires a
storage capacitor to GND. Can be overdriven by
external voltage applied to V
Linear Dimming. Apply a voltage less than
V
Resistor to GND sets the minimum off-time.
Electrical and thermal conductive pad on the
bottom of CPC9909NE. Connect this pad to
ground and provide sufficient thermal coupling
to remove heat from the package.
CS(high)
to dim the LED(s).
