1.4 Inductor

A 1 µH inductor L1, is used in the EVM. With 1 µH inductor, a smaller ripple from a larger valued inductor reduces the magnetic hysteresis losses in the inductor and EMI. If the load current is larger than 1 A, a 0.47 µH inductor is more recommended for better response performance and larger phase margin.
