Texas Instruments DLPA2000DYFFR

Overview

DLPA2000DYFFR from Texas Instruments is a dedicated power management and RGB LED/lamp driver IC for DLP® projector chipsets, integrating buck-boost LED drivers (750 mA max per channel), DMD bias supplies (VOFS = 10 V, VBIAS = 18 V, VRST = –14 V), 1.1-V VCORE synchronous buck converter (600 mA), 1.8-V load switch, motor driver, and analog measurement mux. It enables precise timing-critical illumination control in WVGA DLP2010-based embedded projectors and mobile sensing modules.

For engineers reviewing the DLPA2000DYFFR datasheet, DLPA2000DYFFR pinout, DLPA2000DYFFR application, or DLPA2000DYFFR equivalent, key selection considerations include its integrated DMD power sequencing, independent 10-bit LED current control per channel, 56-ball DSBGA package with 0.4-mm pitch, thermal warning/shutdown thresholds (120 °C / 150 °C), and SPI interface compliance with 33-MHz operation.

Technical Context

The DLPA2000DYFFR implements three independent switch-mode regulators for DMD biasing: VOFS (10 V, ±2% accuracy), VBIAS (18 V, ±2%), and VRST (–14 V, ±3%), each with active discharge and power-good monitoring. Its VLED buck-boost stage operates at 2.25 MHz switching frequency, supports 1.2–5.5 V output range, and delivers up to 750 mA per RGB channel with 30 mΩ typical R_DS(ON) strobe switches (SW4/SW5/SW6).

It integrates a 1.1-V VCORE synchronous buck converter (600 mA max, ±1.5% DC accuracy) with soft-start (250 µs), a 1.8-V load switch (385–505 mΩ R_DS(ON), 200 mA max), and a full H-bridge motor driver (500 mA operating current, 1.9–2.1 Ω total FET resistance). All regulation, sequencing, and protection logic are managed via internal state machine controlled by SPI register writes.

FAQ

What is the maximum supported LED current per channel for DLPA2000DYFFR?

The DLPA2000DYFFR supports up to 750 mA per RGB channel (SW4/SW5/SW6) when configured with a 100-mΩ current sense resistor and operating within recommended input voltage (2.3–6 V) and thermal limits. This value is confirmed in the Electrical Characteristics table (Section 6.6) under "LED CURRENT CONTROL" with register code 0x307h and is validated across –10 °C to 85 °C ambient temperature.

Does DLPA2000DYFFR provide power sequencing for DMD bias rails?

Yes, DLPA2000DYFFR implements mandatory power sequencing for DMD operation: VOFS ramps first (10 V), followed by VBIAS (18 V), then VRST (–14 V), with defined timing intervals (e.g., 10 ms between VOFS and VBIAS enable). This sequence is hard-coded in the internal state machine and triggered automatically upon PROJ_ON assertion, ensuring safe DMD initialization per DLP2010 requirements.

Can DLPA2000DYFFR drive focus lens motors?

Yes, DLPA2000DYFFR integrates a full H-bridge motor driver with AOUT1/AOUT2/BOUT1/BOUT2 outputs, supporting up to 500 mA continuous current and thermal shutdown at 150 °C. It is explicitly designed for focus lens actuation in DLP projector modules and includes motor protection features such as overcurrent trip (0.53–1.16 A) and deglitch timing on control inputs.

What package type and dimensions does DLPA2000DYFFR use?

DLPA2000DYFFR uses a 56-ball DSBGA (Die Size Ball Grid Array) package designated YFF, with nominal dimensions of 3.28 mm × 3.48 mm ± 0.03 mm and 0.4-mm ball pitch. This ultra-compact package is specified in the Device Information table and mechanical drawings of the DLPS043B datasheet, and is optimized for space-constrained DLP module PCB layouts.

Is SPI the only interface available for configuring DLPA2000DYFFR?

Yes, DLPA2000DYFFR uses a dedicated 4-wire SPI interface (SPI_CLK, SPI_CSZ, SPI_DIN, SPI_DOUT) operating up to 33 MHz for all configuration, status monitoring, and real-time control-including LED current setting, fault register readback, and sequencing enable/disable. No I²C, UART, or parallel interface is supported; VSPI must be supplied at 1.65–3.6 V for proper logic-level operation.
