【產品特性】 2.6V to 5.5V Input Voltage Range Adjustable Output from 0.6V to VIN Guaranteed 3.0A Output Current Accurate Reference: 0.6V (+1%) Up to 95% Conversion Efficiency Low Quiescent Current Integrated Low RDS(ON) Upper and Lower MOSFET Switches: 80mΩ Ω Ω Ω Ω and 60mΩΩΩΩΩ Current Mode PWM Operation Fixed Frequency : 1.2MHz 100% Maximum Duty Cycle for Lowest Dropout Internal Soft-Start Over Voltage and Under Voltage Protection Over Temperature and Over Current Protection WDFN3x3-10L Package RoHS Compliant and Halogen Free The uP1728Q is a high efficiency synchronous-rectified buck converter with internal power switches. Fixed 1.2MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency and small package, the uP1728Q is ideally suitable for portable devices and USB/PCIE-based interface cards, where PCB area is especially concerned. With internal low R DS(ON) switches, the uP1728Q is capable of delivering 3.0A output current over a wide input voltage range from 2.6V to 5.5V. The output voltage is adjustable from 0.6V to V IN by a voltage divider. Other features include internal soft-start, chip enable, over- voltage, under-voltage, over-temperature and over-current protections. The uP1728Q is available in a space-saving WDFN3x3-10L package. |
