Pin Description

Pin Number

MIC2860-2D

Pin Name

Pin Function

1

SC

Serial Control Digital input. Do not leave floating.

2

GND

Ground.

3

VIN

Voltage Input. Connect at least 1µF ceramic capacitor between VIN and GND.

4

D2

LED2 driver. Connect LED anode to VIN and cathode to this pin. Do not leave floating.

(1)

5

RSET

Connect an external resistor from this pin to GND to set the maximum LED current. Example,

apply a 9.53kΩ resistor between RSET and GND to set LED current to 30mA at 100% duty

cycle.

6

D1

LED1 driver. Connect LED anode to VIN and cathode to this pin. Do not leave floating.

(1)

Note 1. When driving only 1 LED, connect D1 and D2 in parallel to the LED cathode and adjust the RSET resistor for half the desired output.
