Pin Accessible Features:  
The TPS65400-Q1 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.
