With the help of above part,i need to design 5V/200mA from the input of 16V.I selected inductor value based on the formula given in the TI datasheet and it is 85uh around.inductor ripple is considered as 0.4*Iout.
Output capacitor as per the formula it is around 4.7uf.But with these values i am not getting the desired output in the simulation(simetrix).Could you please suggest the correct value of inductor and capacitor for my application.If it is possible pleae share me the simualtion file.
Input specification are below
1. Nominal operating range 9-16V
2. Generate a 5V +/- 3% output voltage ; output ripple~50mV
3. Output current ~200mA
4. Switching frequency: Around 500 kHz
