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.
