DLPA2000DYFFR

The DLPA2000DYFFR from Texas Instruments is a high-efficiency PMIC/LED driver designed for embedded applications. It integrates a buck-boost DC-to-DC converter, DMD supplies, a core supply, a load switch, and a measurement system within a compact chip-scale package.

This device offers independent 10-bit current control per channel for its three low-impedance MOSFET switches. It supports a maximum LED current of 750mA and includes an on-chip motor driver for DMD regulators. The integrated DPP core supply is a synchronous step-down converter capable of up to 600mA output current, while the VLED buck boost converter operates with an input voltage range of 1.8V to 3.6V and supports up to 200mA of current.

Key electrical features include a 2.7V supply voltage, 2.25MHz switching frequency, and SPI control for dimming. The DLPA2000DYFFR also incorporates a measurement system for analog signals like battery voltage, LED voltage, LED current, and light sensor input. Monitoring and protection circuits are included, such as hot die warning, low-battery warning, programmable undervoltage lockout (UVLO), and overcurrent protection.

The component is housed in a 56-DSBGA package with dimensions of 3.280 mm x 3.484 mm and a 0.4mm pitch. It is designed for surface mount applications and operates within a temperature range of -10°C to 85°C.
