Description for the TPS50601A-SP

TheTPS50601A-SP is a radiation hardened, 7-V, 6-A synchronous step-down converter, which isoptimized for small designs through high efficiency and integrating the high-side and low-sideMOSFETs. Further space savings are achieved through current mode control, which reduces componentcount, and a high switching frequency, reducing the inductor’s footprint. The devices are offeredin an ultra small, thermally enhanced 20-pin ceramic flatpack package.

The output voltage startup ramp is controlled by the SS/TR pin which allows operation aseither a stand alone power supply or in tracking situations. Power sequencing is also possible bycorrectly configuring the enable and the open drain power good pins. In addition, the TPS50601A-SPcan be configured in master-slave mode to provide up to 12-A of output current.

Cycle-by-cycle current limiting on the high-side FET protects the device in overloadsituations and is enhanced by a low-side sourcing current limit which prevents current runaway.There is also a low-side sinking current limit which turns off the low-side MOSFET to preventexcessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermalshutdown temperature.
