A 35A module from Texas Instruments (TI) which features overcurrent protection is now being shipped by Mouser Electronics. It is designed for compact PCI/PCIe, broadband, point-of-load, and medical equipment applications. TI’s PSM846C24 is a fixed-frequency, step-down power module that incorporates a controller, power MOSFETs, inductor, and associated components into a thermally enhanced, surface-mount package.
Setting the operating parameters of the module requires just input and output capacitors as well as a few other passive components.
Engineers can achieve a two-phase power solution by configuring two modules to work in parallel up to 70 A with current sharing.
The power moudle operates at a junction temperature range of minus 40 to 125 degrees Celsius, and is available in a 15 mm × 16 mm footprint that is easy to solder onto a PCB and allows a compact, point-of-load design.
The module is supported by the TPSM846C24EVM-006 and TPSM846C24EVM-007 evaluation modules. Both evaluation modules provide test points and jumpers to facilitate easy testing.
The TPSM846C24EVM-006 contains a single TPSM846C24 module, while the TPSM846C24EVM-007 contains two TPSM846C24 modules working in parallel to enable up to 70A output current.
