N2.1 Characteristics subject to change without notice PIN DESCRIPTION Pin # Name Function 1 LEDC2 LEDC2 cathode terminal 2 LEDC1 LEDC1 cathode terminal 3 LEDB2 LEDB2 cathode terminal 4 LEDB1 LEDB1 cathode terminal 5 LEDA2 LEDA2 cathode terminal 6 LEDA1 LEDA1 cathode terminal 7 VOUT Charge pump output connected to the LED anodes 8 VIN Charge pump input, connect to battery or supply 9 C1+ Bucket capacitor 1 Positive terminal 10 C1- Bucket capacitor 1 Negative terminal 11 C2+ Bucket capacitor 2 Positive terminal 12 C2- Bucket capacitor 2 Negative terminal 13, 14 GND Ground Reference 15 GND Ground Reference 16 EN/SET Device enable (active high) and Dimming Control Top view: TQFN 16-lead 3 X 3 mm TAB TAB Connect to GND on the PCB PIN FUNCTION VIN is the supply pin for the charge pump. A small 1μF ceramic bypass capacitor is required between the VIN pin and ground near the device. The operating input voltage range is from 2.5V to 5.5V. Whenever the input supply falls below the under-voltage threshold (2.2 V), all the LED channels are disabled and the device enters shutdown mode. EN/SET is the enable and one wire addressable control logic input for all LED channels. Guaranteed levels of logic high and logic low are set at 1.3V and 0.4V respectively. When EN/SET is initially taken high, the device becomes enabled and all LED currents remain at 0mA. To place the device into zero current mode, the EN/SET pin must be held low for more than 1.5ms. VOUT is the charge pump output that is connected to the LED anodes. A small 1μF ceramic bypass capacitor is required between the VOUT pin and ground near the device. GND is the ground reference for the charge pump. The pin must be connected to the ground plane on the PCB. C1+, C1- are connected to each side of the ceramic bucket capacitor C1 C2+, C2- are connected to each side of the ceramic bucket capacitor C2 LEDA1 – LEDC2 provide the internal regulated current source for each of the LED cathodes. These pins enter high-impedance zero current state whenever the device is in shutdo wn mode. TAB is the exposed pad underneath the package. For best thermal performance, the tab should be soldered to the PCB and connected to the ground plane |
