SLUUBS4A January 2018 – June 2021 TPSM84209
This EVM features the TPSM84209 synchronous buck power module configured for operation with a 4.5-V to 28-V input voltage range. The output voltage can be set to one of five popular values by using a configuration jumper. The full 2.5-A output current rating of the device can be supplied by the EVM. Input and output capacitors are included on the board to accommodate the entire range of input and output voltages. Monitoring test points are provided to allow measurement of efficiency, power dissipation, input ripple, output ripple, line and load regulation, and transient response. A control test point is provided to control the ENABLE feature and component footprints are provided for UVLO resistors and additional input and output capacitors. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
