The simplest way to increase LED current-EEWORLD

Collect

The simplest way to increase the output power of the transmitter is to drive the LED through a FET or other type of transistor. The figure shows an implementation in which the DRV pin of the MAX44000 drives the pMOSFET on and off, thereby driving the current through the transmitter. The current value is set by R5.
