那么我们可以进行如下计算：1，输出电流Iout=Pout/Udc=600/400=1.5A2，最大输入功率pin=Pout/η=600/0.92=652W3，输入电流最大有效值Iinrmsmax=pin/Umin=652/85=7.67A4，那么输入电流有效值峰值为Iinrmsmax*1.414=10.85A5，高频纹波电流取输入电流峰值的20%，那么Ihf=0.2*Iinrmsmax=0.2*10.85=2.17A6，那么输入电感电流最大峰值为：ILpk=Iinrmsmax+0.5*Ihf=10.85+0.5*2.17=11.94A7，那么升压电感最小值为Lmin=(0.25*Uout)/(Ihf*fs)=(0.25*400)/(2.17*65KHz)=709uH8，输出电容最小值为：Cmin=Iout/(3.14*2*fac*Voutp-p)=1.5/(3.14*2*50*10)=477.7uF，实际电路中还要考虑hold up时间，所以电容容量可能需要重新按照hold up的时间要求来重新计算。实际的电路中，我用了1320uF，4只330uF的并联。

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2µA. The PW4055 can be put into shutdown mode, reducing the supply current to 25µA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage
