1MHz, High-Efficiency, Step-Up Converter for White LEDs

The APW7207/A is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 10 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 reduces power loss and achieves • Wide Input Voltage from 2.5V to 6V\n• 0.2V Reference Voltage\n• Fixed 1MHz Switching Frequency\n• High Efficiency up to 88%\n• 100Hz to 200kHz PWM Brightness Control Frequency\n• Open-LED Protection\n• Under-Voltage Lockout Protection\n• Over-Temperature Protection\n• <1µA Quiescent Current Du;
