Buck Boost Input Capacitor Selection

An input capacitor is required to reduce the input voltage ripple,

input ripple current, and source impedance. Place the input

capacitor as close as possible to the VIN2 pin.

For most applications, the VIN2 pin ties together with the VSYS

pin. The VSYS capacitance is effective, therefore, a 1 μF capacitor

is sufficient for the VIN2 pin. The input capacitor can be

increased without any limit for better input voltage filtering.

Suggested VIN2 capacitors are show in Table 75.

Buck Boost Inductor Selection

Inductor conduction losses are caused by the flow of current

through the inductor, which has an associated internal DCR.

Larger inductors have smaller DCR values that can decrease

inductor conduction losses. Inductor core losses are related to

the magnetic permeability of the core material.

Suggested buck boost inductors are shown in Table 76.

Buck Boost Output Capacitor Selection

Output capacitance is required to minimize the output voltage

overshoot and undershoot and to minimize the output ripple

significantly in hysteresis mode.

Suggested buck boost output capacitors are shown in Table 75.
