Current-Sense Differential Amplifier Positive Input. The differential voltage between CSN and CSP is
amplified internally by the current-sense amplifier (gain = 34.5) to measure the inductor current.
Differential LED Current-Sensing Negative Input. SENSE- is used to sense the LED current. Connect
SENSE- to the negative side of the LED current-sense resistor.
Differential LED Current-Sensing Positive Input. SENSE+ is used to sense the LED current. Connect
SENSE+ to the positive side of the LED current-sense resistor.
Supply Voltage Connection. Connect IN to V

and 0.1µF ceramic capacitors.
Supply Voltage for Low-Side and High-Side Drivers. Connect a parallel combination of 0.1µF and 1µF
ceramic capacitors to PGND and a 1Ω resistor to V
from internal circuitry.
Exposed Paddle. Connect the exposed paddle to a copper pad (SGND) to improve power
dissipation.
CC
is derived from the IN voltage. Bypass V
