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.

Возможности:

This verified reference design is a signal conditioning solution for front-port QSFP+ supporting two 40GbE ports compatible with 40G-CR4/SR4/LR4 and 10G SFF-8431 requirements. The design is applicable to optical and passive/active copper cables. It allows for reach extension between the Switch ASIC and the front-port QSFP+ which is often required for the outermost ports of a Top-of-Rack (ToR) switch or for add-in mezzanine implementations of QSFP+ line cards.

Возможности:

Front-port stacked QSFP+ implementation with signal conditioning to support 40GbE/10GbE optical and passive copper Extends reach between Switch and front-port by up to 3x beyond nPPI/SFF-8431 host channel loss limit Low-power/low-cost solution for front-port signal conditioning Applicable to Top-of-Rack (ToR) switch and line card systems Single power supply, no firmware required, no heatsink required, no reference clock required Lab-tested HW example including 40GbE/10GbE-specific test data

The TIDA-01405 design demonstrates an inverting power module (voltage inverter) to generate a –1.8V rail at up to 2A of current from a 3V to 15.2V input voltage. Such a negative voltage is required for many communications equipment systems as well as industrial equipment, such as test and measurement. Using the TPS82130 power module enables a very simple negative voltage inverter (inverting buck-boost) design to create a 1.8V negative output voltage at high 2A currents.

This small and simple, low-noise inverting power module design (voltage inverter) cleanly supports a –5-V output voltage at up to 1.5 A of current from a 3- to 11.5-V input. Featuring TI’s TPS82130 MicroSiP™ power module step-down converter in an inverting buck-boost topology, the design achieves a power density of 584 mW/mm3 and a solution size of less than 50 mm2, allowing it to power sensitive analog loads in space-constrained, high-temperature communications equipment, such as optical modules. This design also supports many common industrial equipment, including those that require a 5-V input and –5-V output voltage inverter at up to 1 A.
