3 Description
BQ25758 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.
