uP6103 5V/12V Synchronous-Rectified Buck Controller with Reference Input General


The uP6103 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 uP6103 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 function. With aforementioned functions, this part provides customers a compact, high efficiency, well-protected and cost-effective solutions. This part is available in SOP-8 and PSOP-8 packages. † 3.3V to 12V VIN Input Range † 0.6 VREF with 1.5% Accuracy † Output Range from VREF to 80% of VIN † Support Tracking Mode and Stand Alone Mode Operation † Simple Single-Loop Control Design † Voltage-Mode PWM Control † Fast Transient Response † High-Bandwidth Error Amplifier † 0% to 80% Duty Cycle † Lossless, Programmable Overcurrent Protection † Uses Lower MOSFET RDS(ON) † 200/300 kHz Fixed Frequency Oscillator † Internal Soft Start † Integrated Bootstrap Diode † RoHS Compliant and Halogen Free
