Texas Instruments TPSM84424 4A Power Module
Texas Instruments TPSM84424 4A Power Module is an easy-to-use integrated power supply that combines a 4A DC/DC converter with power MOSFETs, a shielded inductor and passives into a small form factor, QFN package. This power solution allows as few as six external components while maintaining the ability to adjust key parameters to meet specific design requirements. Ultra-fast transient response can be achieved by use of the TurboTrans™ feature. TurboTrans allows the transient response to be optimized for reduced output voltage deviation with less required output capacitance. The 7.5 mm × 7.5 mm × 5.3 mm, 24-pin, QFN package is easy to solder to a printed circuit board and has excellent power dissipation capability. The TPSM84424 offers flexibility with many features including power good, programmable UVLO, tracking, prebias start-up, as well as overcurrent and overtemperature protection making it ideal for powering a wide range of devices and systems.
