SNVU581B November 2017 – June 2021 TPSM84424 , TPSM84624 , TPSM84824
This EVM features the TPSM84824/624/424 synchronous buck power module configured for operation with a 4.5-V to 17-V input voltage range. The output voltage can be set to one of six popular values by using a configuration jumper. Similarly, the switching frequency can be set to one of six values with a jumper. Additionally, the RTT resistor value, which selects the TurboTrans feature for improved transient response, is also selectable using a jumper. The full 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. Control test points and component footprints are provided for use of the ENABLE, PGOOD, and CLK features of the device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
