APW7207A Datasheet | ANPEC

APW7207/A 1MHz, High-Efficiency, Step-Up Converter for White LEDs Features General Description - Wide Input Voltage from 2.5V to 6V The APW7207/A is a current-mode and fixed frequency - 0.2V Reference Voltage - Fixed 1MHz Switching 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 iden- - High Efficiency up to 88% tical for uniform brightness. Its low on-resistance of N- - 100Hz to 200kHz PWM Brightness Control Fre- FET and feedback voltage reduces power loss and achieves high efficiency. Fast 1MHz current-mode PWM quency operation is available for input and output capacitors and -...
