Texas Instruments LMZM33604EVM User Manual

LMZM33604EVM and LMZM33606EVM User's Guide
These evaluation modules (EVMs) are designed as an easy-to-use platform that facilitates an extensive
evaluation of the features and performance of the LMZM33604 and LMZM33606 power module. This
guide provides information on the correct usage of the EVMs and an explanation of the numerous test
points on the board.
1 Description
These EVMs feature either the LMZM33604 or LMZM33606 synchronous-buck power module configured
for operation with typical 3.5-V to 36-V input bus applications. The output voltage is set to one of five
popular values by using a configuration jumper. Similarly, the switching frequency is set to one of five
values with a jumper. The EVM supplies the full output current rating of the device. Input and output
capacitors are included on the board 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 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 EN, PGOOD, BIAS, and SYNC features of the
LMZM33606 device. The EVMs use a recommended PCB layout that maximizes thermal performance and
minimizes output ripple and noise.
2 Getting Started
Figure 1 highlights the user interface items associated with the EVM. The VIN Power terminal block (TB1)
is used for connection to the host input supply and the VOUT Power terminal block (TB2) is used for
connection to the load. These terminal blocks accept up to 16-AWG wire.
