STEVAL-ISA063V1 1 A, high efficiency single inductor DC-DC converter based on STBB1
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 batterypowered applications where the output voltage is within the battery voltage range. The integrated low RDSON N-channel and P-channel MOSFET switches contribute to the high efficiency of the STBB1XX device
