USA seller BlackBuck 8M - 8 Amps compact driver for portable devices The brand new high-performance, compact buck LED/laser diode driver with thermal protection (external NTC sensor) . Can be controlled/modulated by an external sources like DAC, PWM or analog modulated signal. It has 5V reference voltage output for connecting an external potentiometer as a modulation source. High-quality onboard multi-turn trimmer helps to the fine-tuning of the output current. The driver can operate with the current up to 3A without an external heat sink, but it requires a heat sink for currents above 3A. It works fine with 2 or 3 cells Li-Ion or Li-Po batteries or 7-12V DC PSU. Specs: Output (drive) current 1000... 8000 mA +/- 5% Modulation input  0...5V or 5V TTL/PWM Conversion efficiency >93% Modulation rise/fall time 40/60ms Start-up delay 30ms Sine-wave modulation bandwidth 4 KHz Overheat protection shutdown t° 50° C / 122° F +/- 5% PCB dimension 16*17*6 mm The connection method using the reference voltage output and an external potentiometer to control the output current:   The connection method using an external signal:   The connection method if you are not using external modulation sources:   The item comes with NTC sensor Avoid short circuit and reverse polarity connection, it will damage the driver! The contact pads on the PCB is very small, if you do not have enough skills in soldering, I highly recommend do not buy this driver.  No returns are new and working
