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最大电流值(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.
