UP6205

Preliminary uP6205 Compact Dual-Pha se Synchronous-Re ctified Buck Controller General Description The uP6205 is a compa ct dual-pha se synchronous-re ctified † Buck controller specifically designed to deliver high quality † output voltage f or high power a pplications. This part is † capable of delivering up to 60Aoutput current owing to its embedded bootstrapped drivers that support 12V + 12V † driving capability. The uP6205 features configurable gate † driving voltage f or maxi mum ef ficiency a nd opti mal performance. The built-in bootstra p diode si mplifies the † circuit design and reduces external part count a nd PCB † space. Features Operate with 4.5V ~13.2V Supply V oltage Support Single- a nd Two- Phase Operation ±2.0% Over Line V oltage and Temperature Simple Single-Loop Voltage-Mode Control 12V Bootstrapped Drivers with Internal Bootstrap Diode Lossless RDS(ON) Current Sensing Adjustable Operation Frequency form 50kHz to 1MHz Per Phase The output voltage is precisely regulated to internal 0.6V † External Compensation 0.4V to 2.5V . The uP6205 or extern al reference voltage from † Adjustable Over Current Protection adopts lossless R DS(ON) current sensing technique for † Adjustable Soft Start channel current bala nce and over current prote ction. A MODE pin progra ms single- or dual- pha se operation † VQFN4x4 - 24L or VQFN3x3 - 16L Package making the uP6205 ideally suita ble for dual power in put † RoHS Compliant and 100% Lead (Pb)-Free applications such a s P...
