STEVAL-ISA063V1: 3.3V @ 1A, 2 ~ 5.5Vin

Summary

The STEVAL-ISA063V1 demonstration board represents a typical buck-boost DC-DC converter application, intended to demonstrate the function and performance of the STBB1XX device. The STBB1XX is a fixed frequency, high efficiency DC-DC converter capable of providing output voltages ranging from 1.2 V to 5.5 V, and input voltages from 2.0 V to 5.5 V.

The STBB1XX device can operate with input voltages higher than, equal to, or lower than the output voltage, making the product suitable for single Li-ion, multi-cell alkaline or NiMH battery powered applications where the output voltage is within the battery voltage range.
