STEVAL-ISA063V2

1 A, high efficiency single inductor DC-DC converter

based on the STBB1-APUR

Features

Description

The STEVAL-ISA063V2 demonstration board

implements a typical buck-boost DC-DC

converter based on STMicroelectronics’ STBB1-

APUR high efficiency single inductor dual mode

buck-boost DC-DC converter.

The device is fixed frequency and 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 STBB1-APUR can operate with input

voltages higher than, equal to, or lower than the

output voltage, rendering the product suitable for

single lithium-ion (Li-Ion), multicell alkaline or

NiMH applications where the output voltage is

within the battery voltage range.

channel MOSFET switches contribute to its high

efficiency.
