TPS65400 Synchronous Quad Converter

Texas Instruments' 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. It 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.

TPS65400 implements a PMBus-I2C-compatible digital interface. It helps Core Chip optimize system performance by runtime changing regulated voltage, power sequence, phase interleaving, operating frequency, read back operating status, and so forth.
