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
