Does EPC have application information on the use of GaN transistors in LED illumination applications?
The use of LEDs for illumination (not just backlighting) has proliferated in recent years and there are numerous applications and topologies. The EPC9001 and EPC9002 development boards can be used to create LED backlighting solutions with very high contrast ratio, but are designed for buck / half-bridge type topologies. For anyone experienced in the art it is possible to operate this ‘backwards’ as a synchronous boost – noting that the input PWM will now be complimentary to what is required. Care should be taken in doing so as the output bus voltage can easily be boosted above the rated maximum voltage. To get more information about EPC’s growing list of development and demo boards, or to purchase these boards, go to the Demo Boards page.
