PMP8999
概述
It is a two phase Synchronous Buck converter to provide high current with low ripple and fast dynamic response for high speed processor core applications. Same approach can also be used to power Memory and Input / Output power voltages, typically 1.2V to 3.3V. The two phase interleave reduces output ripple and allows faster response to rapidly changing loads. The two phases distribute power loss to eliminate need for added heat sink hardware. The "Project File" for the TPS40422 to communicate with TI's Fusion GUI is included. Output voltage and current limit can be adjusted and monitored thru the GUI. Additional settings can be accessed thru the same GUI. Test Report includes thermal images to show load capability, both with and without fan cooling. Testing done at 12Vin, where voltage stresses, losses and output ripple greatest. Design will work also at 5Vin with same high speed control loop, due to Input Voltage Feed Forward in the TPS40422.
