Abstract

The TPSM5601R5EVM features the TPSM5601R5 synchronous-buck power module and the TPSM5601R5SEVM features the TPSM5601R5S synchronous-buck power module which offers frequency spread-spectrum operation. Both EVMs are configured for operation with typical 4.2-V to 60-V input bus applications. The output voltage is set to one of five popular values by using a configuration jumper. The EVM supplies the full output current rating of the device. Input and output capacitors are included to accommodate the entire range of input voltage and the selectable output voltages on the EVM. Monitoring test points are provided to allow measurement of the following:

• Efficiency
• Power dissipation
• Input ripple
• Output ripple
• Line and load regulation
• Transient response

Control test points and jumpers are provided for use of the enable (EN) and power-good (PGOOD) features of the device. The recommended PCB layout of the EVM maximizes thermal performance and minimizes output ripple and noise.
