UP6103S8 5V/12V Synchronous-Rectified Buck Controller with Reference Input General


The UP6103S8 is a compact synchronous-rectified buck controller specifically designed to operate from 5V or 12V supply voltage and to deliver high quality output voltage as low as 0.4V. These SOP-8 and PSOP-8 devices operate at fixed 200/300 kHz frequency and provide an optimal level of integration to reduce size and cost of the power supply. The UP6103S8 supports both tracking mode and stand-alone mode operation. The output voltage is tightly regulated to the external reference voltage from 0.4V to 3.0V at tracking mode or to internal 0.6V reference at stand-alone mode. This controller integrates internal MOSFET drivers that support 12V+12V bootstrapped voltage for high efficiency power conversion. The bootstrap diode is built-in to simplify the circuit design and minimize external part count. Other features include internal softstart, undervoltage protection, overcurrent protection and shutdown f [ … ]
