Download PT Datasheet. The device operates from an input supply between 6V and 30V and provides an externally adjustable output current of up to 1. Depending upon the supply voltage and external components, the PTcan provide more than 30 watts of output power. The PT includes the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current, and a dedicated DIM input accepts either a DC voltage or a wide range of pulsed dimming.

Hi, this system will not work with current above 1. As long as PT will know what current flows through the system using a Rsense resistor it will limit the mosfet transistor.
