Description

  • TPS40222EVM-001 evaluation module (EVM) is a nonsynchronous buck converter with a 4.5V to 8V input range with a built-in N-channel power FET, that can deliver 1.6A of output current. The EVM is designed to operate with a minimum of components and yet has the features of more complex buck converters. The TPS40222EVM-001 is designed to use a 4.5 to 8V input voltage to produce a high-current, regulated 1.4V output at up to 1.6A of load current. This application board is designed to demonstrate the TPS40222 in a typical voltage bus to low-voltage application while providing a number of test points to evaluate the performance of the IC. Users can modify the EVM to support output voltages from 0.8V to 6.3V by changing a single resistor. The TPS402224EVM-001 was built to the application example used in the TPS40222 data sheet with the internal clock operating at 1.25MHz
