Step-up Converter

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 h Wide Input Voltage from 2.7V to 6V\n0.25V Reference Voltage\nFixed 1MHz Switching Frequency\nHigh Efficiency up to 87%\n100Hz to 100kHz PWM Brightness Control Frequency\nOpen-LED Protection\nUnder-Voltage Lockout Protection\nOver-Temperature Protection\n<1mA Quiescent Current Dduring Shutdown\nS;
