The uP6007 is a compact high-efficiency step-up converter
with integrated switch specifically designed to drive up to
10 white LEDs in series. Series connection of the LEDs
provides identical current resulting in uniform brightness.
Fixed 1.0MHz/500kHz operation allows smallest output
ripple and external component size. With high conversion
efficiency and small package, the uP6007 is suitable for
portable devices which PCB area is especially concerned.
The white LED current is set by an external resistor and
the feedback voltage is regulated to 200mV. During
operation, the LED current can be controlled by PWM input
signal in which the duty cycle determines the feedback
reference voltage。uP6007PDN8 uP6007QDN8资料下载
