Overview
The TPSM84424MOLR is a highly integrated power module from Texas Instruments, designed to provide a compact and efficient power solution. This module combines a 4-A DC/DC converter with power MOSFETs, a shielded inductor, and necessary passives into a small form factor QFM package. The device is easy to use and requires as few as six external components, making it ideal for space-constrained applications. It offers adjustable key parameters to meet specific design requirements and features an ultra-fast transient response thanks to the TurboTrans™ feature.
