Description
AI
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 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.
