DC/DC 升压变换芯片

TP83 系列芯片是采用 CMOS 工艺制造的静态电流极低的 VFM 开关型 DC/DC 升压转换器。该芯片由振荡器、VFM 模式控制电路、Lx 开关驱动晶体管、基准电压单元、误差比较放大器、电压采样电阻及 VLX限幅电路等组成。\r\n\r\n TP83 系列升压转换器采用变频的方式，因此较国内外同类产品具有更低的纹波、更强的驱动能力、效率高等特点，应用时外围只需接三个元件(电感、电容及二极管各一个)。输入电压最低 0.8V,并且可以根据要求调整输出电压 3V—6V 可选。 1. 外接元件少：需肖特基管、电感及电容各一个；外接元件建议选择: 低直流电阻电感 20～220μH，钽电容 47～\r\n200μF，肖特基二极管。\r\n2. 极低的静态电流：4uA\r\n3. 低噪声及低纹波：纹波典型值为 100mV\r\n4. 驱动能力强：\r\n Vtyp=3.3V, Vin=1.0V 时，Iout=100mA\r\n Vtyp=3.3V, Vin=3.0V 时，Iout=750mA\r\n5. 启动工作电压低：最大 0.8V\r\n6. 高效率：85%(Typ)\r\n7. 封装体积小：SOT23（窄体）;
