The AP3583/A is a simple single-phase synchronous buck controller. It operates from 5V or 12V supply voltage and delivers high quality output voltage as low as 0.6V. This device operates at fixed 200kHz (AP3583) or 300kHz (AP3583A) frequency and provides an optimum compromise between efficiency, external component size and cost. With integrated linear regulator bootstrap diode, and N-Channel MOSFET gate drives, the AP3583/A can reduce external component count and board space requirements. The AP3583/A supports both tracking mode and stand-alone mode operation. The output voltage is tightly regulated to the external reference voltage from 0.4V to 3V at tracking mode or internal 0.6V reference at stand-alone mode. Other features include internal soft-start, under voltage protection, over current protection and shutdown function. With aforementioned functions, this part provides customers a compact, high efficiency, well-protected and cost-effective solutions. The AP3583/A is available in PSOP-8 package.
