TPS65400 Overview
The TPS65400 is an integrated PMU optimized for applications requiring small form factor and high power conversion efficiency, enabling small spaceconstrained 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 bination of regulators. Device...
