The brand new high-performance, compact buck LED/laser diode driver with interlock input . The driver can operate without an external heat sink with the current up to 1.5A , but it requires a heat sink for currents above 1.5A. It works fine with 2 or 3 cells Li-Ion or Li-Po batteries or 7-12V DC PSU.
