3 Description
BQ25758S is a bidirectional switched-mode buckboost
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 buck-boost 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.
