Texas Instruments High-Performance Analog Specialized ICs - DLPA3000CPFDR DLPA3000CPFDR

The DLPA3000CPFDR is a highly integrated power management IC designed specifically for DLP Pico Projector systems. It features a high-efficiency, high-current RGB LED driver capable of delivering up to 6 A per LED, supported by an integrated buck converter. The device includes RGB MOSFET switches with low on-resistance for effective channel selection and offers 10-bit programmable current control for each channel. Additionally, the DLPA3000CPFDR incorporates multiple buck converters, including two dedicated for generating low-voltage supplies for the DLPC343x and DMD, as well as an 8-bit programmable buck converter for auxiliary applications such as driving a fan. It also provides two low-dropout regulators (LDOs) for auxiliary voltage supplies of up to 200 mA, preset to 2.5 V and 3.3 V. The IC includes monitoring and protection features such as thermal shutdown, hot die detection, low-battery monitoring, and undervoltage lockout (UVLO), making it suitable for portable applications. Engineers considering this product should note its specific application in portable DLP projectors and its capabilities in managing high-current LED driving and power supply requirements.
