The Texas Instruments TPS61043DRBRG4 is a high-frequency boost converter with a constant current output, suitable for driving white LEDs in applications like display backlights for PDAs, smartphones, and handheld devices. It operates with an input voltage range of 1.8 V to 6 V and provides an output voltage of up to 16.9 V with a typical output current of 60 mA. The device features precise brightness control using PWM or analog signals, with a PWM frequency range of 100 Hz to 50 kHz.
Key features include an internal 30-V switch, up to 85% efficiency, and integrated 18-V overvoltage protection for enhanced safety. It can power up to 4 LEDs in series and operates with small output capacitors. The TPS61043DRBRG4 is available in a compact 3-mm x 3-mm 8-SON package, designed for surface mounting, making it ideal for space-constrained designs.
This LED driver IC offers a shutdown current of 0.1 µA typical and a no-load quiescent current of 38 µA typical. The device disconnects LEDs during shutdown to prevent leakage currents. Its switching frequency can reach up to 1 MHz, and it operates within a temperature range of -40°C to 85°C.
