TPS65400/TPS65400-Q1 Power Management Unit (PMU)

Texas Instruments TPS65400/TPS65400-Q1 Integrated Power Management Unit (PMU) is an integrated PMU optimized for applications requiring a 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. The TPS65400/TPS65400-Q1 implements a PMBus-I²C-compatible digital interface. It helps the Core Chip optimize system performance by runtime changing regulated voltage, power sequence, phase interleaving, operating frequency, read back operating status, and so forth. The Texas Instruments TPS65400-Q1 devices are AEC-Q100 qualified for automotive applications.
