4.5 V to 18 V input, 4 A / 4 A / 2 A / 2 A synchronous quad converter with PMBus/I2C interface

The TPS65400 is an integrated PMU optimized for applications requiring small form factor and high power conversion efficiency, enabling small space-constrained equipment with high ambient operating temperature without cooling. The device provides high-power efficiency at a system level by enabling a single stage conversion from an intermediate distribution bus with an optimized combination of regulators.
