基于Saber的单相Boost电路仿真与设计
An input capacitor value of 10 μF is normally recommended to improve transient behavior of the regulator and EMI behavior of the total power supply circuit.The TPS61099x is optimized to work with the inductor from 1 µH to 2.2 µH, so the minimal output capacitor value is 20 μF (...
