نظرة عامة على المنتج
The DLPA3000DPFDR is a highly integrated power management IC (PMIC) and high-current RGB LED driver from Texas Instruments, optimized for DLP Pico Projector systems. It features an integrated buck converter enabling up to 6 A per LED, RGB MOSFET switches for color sequencing, generation of DMD high-voltage supplies (VBIAS, VRST, VOFS), and multiple buck converters for system power. The device supports accessory projector applications up to several hundred lumens.
