TPS40041EVM-001
概述
The TPS40041EVM-001 evaluation module (EVM) is a synchronous buck converter providing a fixed1.8 V output at up to 6 A from a 5 V input bus or 3 A from a 3.3 V input. The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. The module uses the TPS40041 Reduced Pin Count Low-Voltage Synchronous Buck Controller. TPS40041EVM-001 is designed to use a regulated 5 V (4.5 V to 5.5 V) or 3.3 V (3.0 V to 3.6 V) bus to produce a medium current, regulated 1.8 V output at up to 6 A of load current. TPS40041EVM-001 is designed to demonstrate the TPS40041 in a typical regulated bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40041 in a given application. The EVM can be modified to support output voltages from 0.9 V to 2.5 V by changing a single set resistor.
