1 High-Density EVM Description

The TLVM13660EVM features the TLVM13660 synchronous buck power module configured for operation with typical 3-V to 36-V input bus applications. This wide-VIN range DC/DC solution offers outsized voltage rating and operating margin to withstand supply-rail voltage transients.

The output voltage and switching frequency can each be set to one of five popular values by using configuration jumpers. The EVM provides the full 6-A output current rating of the device. The selected input and output capacitors accommodate the entire range of input voltage and the selectable output voltages on the EVM and are available from multiple component vendors. Input and output voltage sense terminals and a test point header facilitate measurement of the following:

  • Efficiency and power dissipation
  • Line and load regulation
  • Load transient response
  • Bode plot measurement (crossover frequency and phase margin)
The header also provides connections for enable ON/OFF (EN) and power good (PGOOD) indication. The recommended PCB layout maximizes thermal performance and minimizes output ripple and noise.
