uP1707S

uP1707S 3A, 23V, 340K High-Efficiency Synchronous-Rectified Buck Converter General Description Features The uP1707S is a high-efficiency synchronous-rectified † 4.5V to 23V Input Voltage Range buck converter with internal power switch. With internal † Adjustable Output from 0.925V to 20V low RDS(ON) switches, the high-efficiency buck converter is capable of delivering 3A output current over a wide input † 3A Output Current voltage range from 4.5V to 23V. The output voltage is † Accurate Reference: 0.925V ( +1.5%) adjustable from 0.925V to 20V by a voltage divider. Other † Up to 95% Conversion Efficiency features for the buck converter include adjust soft-start, chip enable, over-voltage, under-voltage, over- † Integrated Low RDS(ON) Upper and Lower MOSFET temperature and over-current protections. It is available Switches: 100mΩ in a space saving PSOP-8L package. † Current Mode PWM Operation Ordering Information † † Constant 340kHz Fixed-Frequency Operation...
