Dual Output Synchronous Buck Converter
1
Introduction
The TPS40322EVM-679 evaluation module (EVM) is a dual output synchronous buck converter. The EVM
delivers 1.2 V at 10 A and 1.8 V at 10 A from a 12-V nominal DC input voltage. The module uses the
TPS40322 Dual Output or Two-Phase Synchronous Buck Controller and the CSD86330Q3D Synchronous
Buck NexFET
delivers 1.2 V at 10 A and 1.8 V at 10 A from a 12-V nominal DC input voltage. The module uses the
TPS40322 Dual Output or Two-Phase Synchronous Buck Controller and the CSD86330Q3D Synchronous
Buck NexFET

Description
TPS40322EVM-679 is designed to use a regulated 8.0-V
DC
to 15.0-V
DC
bus to produce two high-current,
regulated outputs. Both outputs are capable of supplying up to 10 A of load current. The
TPS40322EVM-679 is designed to demonstrate the TPS40322 in a typical regulated bus to dual-output,
low-voltage application while providing a number of test points to evaluate the performance of the
TPS40322 in a given application.
