Booster Interface
EZ-Host has an onchip power booster circuit for use with pow-
er supplies that range between 2.7V and 3.6V. The booster
circuit boosts the power to 3.3V nominal to supply power for
the entire chip. The booster circuit requires an external induc-
tor, diode, and capacitor. During power down mode, the circuit
is disabled to save power. The figure below shows how to con-
nect the booster circuit.
