  • TD8202

  • TD8202 1MHz, High-Efficiency, Step-Up Converter for 2 to 8 White LEDs

    (DATASHEET)


    The TD8202A/B/C is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 8 white LEDs in series.
    The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and feedback voltage reduce power loss and achieve high efficiency. Fast 1MHz current-mode PWM operation is available for input and output capacitors and a small inductor while minimizing ripple on the input supply. The OVP pin monitors the output voltage and stops switching if exceeds the over-voltage threshold. An internal softstart circuit eliminates the inrush current during start-up.
    The TD8202A/B/C also integrates under-voltage lockout, over-temperature protection, and current-limit circuits. The TD8202/A/B/C is available in a SOT-23-6 packages
