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.
