AL264

SD6271为一颗CC(恒流)模式的PWM升压IC,适用于锂电池（3～4.2V）输出5V,1A的移动电源应用。  SD6271封装为SOT23-6,工作频率为1MHZ,可以搭配3.3uh小型贴片电感，减少成品体积。   SD6271内置过温保护，关断保护，欠压保护，过流保护，并可以外接电阻调整*大电流值（0.5～2.5A） The SD6271is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2? power  MOSFET make this regulator highly power efficient. The internal compensation network also minimizes  as much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current. The SD6271 is available in the SOT23-6L package and provides space-saving PCB for the  application fields.   Features   Adjustable Output up to 12V  Internal Fixed PWM frequency: 1.0MHz Precision Feedback Reference Voltage: 0.6V (&plu*n;2%)  Internal  0.2 , 2.5A, 16V Power MOSFET  Shutdown Current: 0.1AOver Temperature Protection  Over  Voltage  Protection   Adjustable Over Current Protection: 0.5A ~ 2.5A   Package:  SOT23-6L  Applications Chargers  Displays Di*al Cameras  Handheld  Devices  Portable Products   Chargers   LCD  Displays   Di*al  Cameras Handheld  Devices Portable  Products
