The Texas Instruments TPS61043DRBT is a high-frequency boost converter with a constant current output designed for driving white LEDs. It features an input voltage range from 1.8V to 6V and can deliver up to 60mA of LED current. The device supports precise brightness control using PWM signals, with a switching frequency up to 1MHz.
Key features include an internal 30V switch, up to 85% efficiency, and overvoltage protection up to 18V. The TPS61043DRBT is available in a compact 3mm x 3mm 8-SON package, making it suitable for space-constrained applications such as backlighting for PDAs, smartphones, and handheld devices.
This LED driver IC disconnects LEDs during shutdown to prevent leakage currents. It operates within a temperature range of -40°C to 85°C. The device is designed to work with small output capacitors, down to 100nF.
