The device is targeting accessory Driver Current applications up to several hundreds of lumen. • RGB MOSFET Switches for Channel Selection The DLPA3000 supports LED projectors up to 6 A With Very Low On-Resistance per LED, enabled by an integrated high efficiency • 10-Bit Programmable Current per Channel buck converter. On top of that, the low-ohmic RGB • Inputs for Selecting Color-Sequential RGB LEDs switches support the sequencing of red, green, and blue LEDs. The DLPA3000 contains five buck • Generation of DMD High-Voltage Supplies converters with two dedicated for DLPC low-voltage • Two High-Efficiency Buck Converters to Generate supplies. Another dedicated regulating supply the DLPC343x and DMD Supply generates the three timing-critical DC supplies for the • Three High-Efficiency, 8-Bit Programmable Buck DMD: VBIAS, VRST, and VOFS. Converters for FAN Driver Application or General The DLPA3000 contains several auxiliary blocks Power Supply (PWR6 currently supported, others which can be used in a flexible way. This enables a will be available in the future) tailor-made Pico Projector system. Three 8-bit • Two LDOs Supplying Auxiliary Voltages programmable buck converters (not all supported yet) can be used, for example, to drive the projector FANs • Analog MUX for Measuring Internal and External or to make auxiliary supply lines. Two LDOs can be Nodes (such as a thermistor and reference levels) used for a lower-current supply of up to 200 mA. • Monitoring/Protections: Thermal Shutdown, Hot These LDOs are pre-defined to 2.5 V and 3.3 V. Die, Low-Battery, and Undervoltage Lockout Through the SPI, all blocks of the DLPA3000 can be addressed. Features included are the generation of 2 Applications the system reset, power sequencing, input signals for Portable DLP® Pico™ Projectors sequentially selecting the active LED, IC self- protections, and an analog MUX for routing analog information to an external ADC.
