Pin Assignment of FP6731 Ordering Information SOT-23-3 Marking Part Number Product Code FP6731-30S3G T8= SOT-23-5 Marking Part Number Product Code FP6731-32S5G aX= Description The FP6731 is a high efficiency PWM DC/DC step -up Converter with internally compensated current mode controller. The 250kHz switching frequency minimizes the size of external components. The output voltage is internally set and a 1A switch is built in the IC. The FP6731 starts up below 1V input voltage with 1mA load. Due to built-in automatic PWM/PFM switch-over function, the FP6731 is able to get high efficiency during both light and heavy load.
