The DLPA3005 supports LED projectors up • Drivers for External RGB Switches to 16 A per LED, enabled by an integrated high efficiency buck controller. Additionally, the drivers • 10-Bit Programmable Current per Channel control the RGB switches, supporting the sequencing • Inputs for Selecting Color-Sequential RGB LEDs of R, G, and B LEDs. The DLPA3005 contains five • Generation of DMD High Voltage Supplies buck converters, two of which are dedicated for DLPC low voltage supplies. Another dedicated • Two High Efficiency Buck Converters to Generate regulating supply generates the three timing-critical the DLPC343x and DMD Supply DC supplies for the DMD: VBIAS, VRST, and VOFS. • Three High Efficiency, 8-Bit Programmable Buck Converters for FAN Driver Application or General The DLPA3005 contains several auxiliary blocks which can be used in a flexible way. This enables a Power Supply. General Purpose Buck2 (PWR6 tailor-made Pico Projector system. Three 8-bit currently supported, others may be available in programmable buck converters can be used, for the future) instance, to drive rgb projector FANs or to make • Two LDOs Supplying Auxiliary Voltages auxiliary supply lines. General Purpose Buck2 • Analog MUX for Measuring internal and external (PWR6) currently supported, others may be available nodes such as a thermistor and reference levels in the future. Two LDOs can be used for a lower- current supply, up to 200 mA. These LDOs are pre- • Monitoring/Protections: Thermal Shutdown, Hot defined to 2.5 V and 3.3 V. Die, Low-Battery, and Undervoltage Lockout (UVLO) Through the SPI, all blocks of the DLPA3005 can be addressed. Features included are the generation of the system reset, power sequencing, input signals for 2 Applications sequentially selecting the active LED, IC self- Portable DLP® Pico™ Projectors protections, and an analog MUX for routing analog information to an external ADC.
