TD8202 - Step-Up Converter

Key Features

  •   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.

T  echcode® DATASHEET       1MHz, High-Efficiency, Step-Up Converter for 2 to 8 White LEDs TD8202 General Description  Features    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.
