The TinySine LED constant current driver is an economical and easy to use driver that will allow you to control LEDs/LED strip. Power in supplied to this LED Driver with a wide range of input voltages (6v to 16v) connected to the VCC header, and DIM pin driven with standard 3.3v or 5v logic. Power in GND connect with signal GND.

The DIM pin are provided for dimming control. Dimming can be done by an analog voltage (20%-100% of max current by varying voltage from .5V-2.5V) or by PWM (so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V) for a full 0-100% range.

TinySine LED Driver supports PWM control so long as the signal is above a minimum of ~1.5V and each LED is driven to ~600mA. That current can be reduced by either presenting an analog voltage or a PWM signal to the board. Please check your LED max acceptable current before you feed it with 100% 600mA current. Or you may burned your LED.

You can increase the maximum current of the LED driver board up to 1A per channel; to do so, replace the current sense resistor with smaller values. To calculate the new value for the resistor, use this formula: ILED = 0.1 / Rset. Thus, for a 1A current, you’d want a .1Ω resistor. Don’t forget to be wary of current ratings; at 1A, the sense resistor will be dissipating 1/10W, so you probably want a resistor of at least 1/8W rating. The package is a standard 0805.
