2 Description

The TPS40100EVM-001 is designed to use a regulated 12-V ±10% (10.8 V–13.2 V) bus to produce a regulated 3.3-V output at up to 10 A of load current. The EVM is designed to demonstrate the TPS40100 in a typical regulated bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40100. The EVM includes features to demonstrate voltage tracking, margin up/down, enable/disable, and power good. A synchronization pin is provided to allow the EVM to be synchronized to an external clock.
