SLVUAV5B March 2017 – February 2022 TPSM846C23
The TPSM846C23 is a highly integrated, PMBus enabled, synchronous buck 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 ranges 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 may be achieved when designing with the TPSM846C23 power module. Monitoring test points are provided to allow measurement of efficiency, power dissipation, input ripple, output ripple, line and load regulation, and transient response. Additionally, control test points are provided for use of the power good, enable control, and synchronization features of the device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
