BQ25758 and BQ25758A Evaluation Modules
Description
The BQ25758 and BQ25758A evaluation modules
(EVM) are complete evaluation systems for the
BQ25758 and BQ25758A ICs. The BQ25758EVM and
the BQ25758AEVM have a max input and output of
55V and a max output current of 10A.
The BQ25758 and BQ25758A ICs are wide voltage,
bidirectional switched-mode buck-boost controllers.
These devices offer high-efficiency power conversion
over a wide voltage range with output CC-CV control.
These ICs have a wide input range of 4.2V to 60V and
a wide output range of up to 60V.
