3 Description

BQ25758A is a wide input voltage, bidirectional

switched-mode buck-boost controller. The device

offers high-efficiency power conversion over a wide

voltage range with output CC-CV control. The device

integrates all the loop compensation for the buckboost

converter, thereby providing a high density

solution with ease of use. In reverse mode, the device

draws power from the output supply and regulates the

input terminal voltage with an added constant current

loop for protection.

Besides the I2C host-controlled mode, the device also

supports programmable hardware limits. Input current,

and output current regulation targets can be set with

single resistor on the IIN, and IOUT pins, respectively.

By default, the device is programmed to provide 5V

output, and the target output voltage can be adjusted

via the VOUT_REG register bits.
