Description

The TPSM846C24 device is a synchronous buck power module designed to provide up to 35 A of output current. The TPSM846C24 can be paralleled with two devices to achieve output current up to 70 A. The TPSM846C24 is a highly integrated, 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 from 4.5 V to 15 V. The output voltage range is from 0.5 V to 2 V.

This evaluation module is designed to demonstrate the ease-of-use and small printed-circuit-board area that can be achieved when paralleling two TPSM846C24 power modules. Monitoring test points are provided to allow measurement of the following:

  • Efficiency
  • Power dissipation
  • Input ripple
  • Output ripple
  • Line and load regulation
  • Transient response

Additionally, control test points are provided for use of the power good, enable control, and undervoltage lockout (UVLO) features of the device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
