30A SIMPLE SWITCHER(R) Power Module with 3 to 14.5V Reference Design with PMBus (PMP9464)
The reference design PMP9464 utilizes the LMZ31530, a 30A SIMPLE SWITCHER® Power Module. The LMZ31530 SIMPLE SWITCHER® power module is an easy-to-use integrated power solution that combines a 30-A DC/DC converter with power MOSFETs, a shielded inductor, and passives into a low profile, QFN package. This design has a LM25056 on the front end. The LM25056 combines high performance analog and digital technology with a PMBus compliant SMBus/I2C interface to accurately measure the operating conditions of electrical systems including computing and storage blades connected to a backplane power bus. This allows the user to monitor the real time values of Vin, Iin, Pin and Pout; as well as temperature and peak power. These values are reported via PMBus™/SMBus™/I2C. PMP9464 also enables the user to margin the output voltage setting, by slewing it up or down. This is done with the LM10011 VID programmable current DAC. The LP2951 supplies a 3.3V rail for the LM3881 power sequencer. The LM3881 sequencer can be used for sequencing other off board power supplies.
Adjustable from 0.6V to 3.3 Vout 30W Pout for powering wide range of FPGA core rails and asics Peak Efficiency at 85% for 0.9V Switching Frequency 500kHz Design ideal for Power Characterization during design phase and subsequent cost saving
