DLPA3005
- High-efficiency, high-current RGB LED driver
- Drivers for external buck FETs up to 16 A
- Drivers for external RGB switches
- 10-bit programmable current per channel
- Inputs to select color-sequential RGB LEDs
- Generation of DMD high voltage supplies
- Two high efficiency buck converters to generate the DLPC343x and DMD supply
- One high efficiency, 8-bit programmable buck converter for fan driver application or general power supply. General purpose buck2 (PWR6) is currently supported.
- Two LDOs supplying auxiliary voltages
- Analog MUX for measuring internal and external nodes such as a thermistor and reference levels
- Monitoring/protections: thermal shutdown, hot die, and undervoltage lockout (UVLO)
The DLPA3005 is a highly-integrated power management IC optimized for DLP Pico™ Projector systems. The DLPA3005 supports LED projectors up to 16 A per LED and up to 32 A for series LEDs, enabled by an integrated high efficiency buck controller. Additionally, the drivers control the RGB switches, supporting the sequencing of R, G, and B LEDs. The DLPA3005 contains five buck converters, two of which are dedicated for DLPC low voltage supplies. Another dedicated regulating supply generates the three timing-critical DC supplies for the DMD: VBIAS, VRST, and VOFS.
The DLPA3005 contains several auxiliary blocks which can be used in a flexible way. This enables a tailor-made Pico Projector system. One 8-bit programmable buck converter can be used, for instance, to drive rgb projector FAN or to make auxiliary supply line. General purpose buck2 (PWR6) is currently supported. Two LDOs can be used for a lower-current supply, up to 200 mA. These LDOs are predefined to 2.5 V and 3.3 V.
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 sequentially selecting the active LED, IC self-protections, and an analog MUX for routing analog information to an external ADC.
