Pin Functions

PIN I/O DESCRIPTION
NAME NO.
CSP QFN
VIN B1 8 I Input supply pin of the device
EN A2 2 I Enable pin. This pin needs to be pulled high to enable the device. To allow brightness control of the LEDs, a PWM signal up to 1 kHz can be applied. This pin has an internal pulldown resistor.
GND A1 1 Analog ground
PGND C3 5 Power ground
FB B3 4 I This is the feedback pin of the device. The feedback pin regulates the LED current through the sense resistor by regulating the voltage across Rs. The feedback voltage is set by the ILED pin. ILED=GND sets the feedback voltage to 500 mV. ILED=high sets the feedback voltage to 250 mV. Refer to digital brightness control section for more information.
OUT C1 7 O Output of the device
SW C2 6 I Switch pin of the device
ILED A3 3 I Digital brightness control input. When this pin is grounded, the digital brightness control is disabled. When this pin is connected to high, then the feedback voltage is reduced to typically
250 mV and the digital brightness control is enabled. Refer to digital brightness control section for more information.
PowerPAD™ – – The PowerPAD™ (exposed thermal diepad) is only available on the QFN package. The PowerPAD™ needs to be connected and soldered to analog ground (GND).
