Descripción de TPS50601A-SP
The TPS50601A-SP is a radiation hardened, 7-V, 6-A synchronous step-down converter, which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and a high switching frequency, reducing the inductor’s footprint. The devices are offered in 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 as either a stand alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins. In addition, the TPS50601A-SP can 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 overload situations 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 prevent excessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.
