SLVUB26D May 2017 – February 2022 TPSM846C23
The TPSM846C23 is a PMBus™ enabled, synchronous buck power module designed to provide up to 35 A of output current. The TPSM846C23 can be paralleled with two devices to achieve output current up to 70 A. The TPSM846C23 is a highly integrated, PMBus-enabled DC-DC power module that combines a 35-A DC/DC converter with power MOSFETs, a shielded inductor, some input and output capacitors, and passives into a low profile package. The input voltage range is 4.5 V to 15 V. The output voltage range is 0.35 V to 2 V. The PMBus interface provides for converter configuration as well as monitoring of key parameters including output voltage, output current, and the internal die temperature, as well as many user-programmable configuration options.
This evaluation module is designed to demonstrate the ease-of-use and small printed-circuit-board area that can be achieved when paralleling two TPSM846C23 power modules. Monitoring test points are provided to allow measurement of the following:
Additionally, control test points are provided for use of the power good and synchronization features of the device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
