TPS65400 Synchronous Quad Converter

4.5 to 18 V input, 4/4/2/2 amp, synchronous quad converter with PMBus/I²C Interface from Texas Instruments

Image of Texas Instruments TPS65400 Synchronous Quad ConverterTexas 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.
