The TPSM63603EVM features the TPSM63603 synchronous-buck power
module configured for operation with typical 3-V to 36-V input bus applications (the
TPSM63603SEVM features the TPSM63603S; spread spectrum variant). The output voltage
and switching frequency can be 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),
synchronization (SYNC), and power-good (PGOOD) features of the device. The
recommended PCB layout of the EVM maximizes thermal performance and minimizes output
ripple and noise. All feature test points, schematic and layout are the same for
both EVMs, TPSM63603EVM and TPSM63603SEVM, the only difference being the U1 IC (see
the device data sheet for information).
