LMZ36002
Simple Switcher® Power Module Evaluation Module
The LMZ36002EVM evaluation module is designed as an easy-to-use platform that facilitates an extensive
evaluation of the features and performance of the Simple Switcher® power module. This guide provides
information on the correct usage of the EVM and an explanation of the numerous test points on the board.
1 Description
This EVM features the LMZ36002 synchronous buck power module configured for operation with typical
12-V to 60-V input bus applications. The output voltage can be set to one of five popular values by using a
configuration jumper. In similar fashion, the switching frequency can be set to one of five values with 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 are provided for use of
the slow-start/tracking, Inhibit/UVLO, PWRGD, and synchronization features of the LMZ36002 device. The
EVM uses 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 polarized PVin Power terminal
block (TB1) is used for connection to the host input supply and the polarized Vout Power terminal block
(TB2) is used for connection to the load. These terminal blocks can accept up to 16-AWG wire. Verify the
polarity of the PVIN and PGND connections for TB1 based on the label beneath the terminal block.
