3 Description
The TPS50601-DIE is a 6.3-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 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.
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.

(2) Processing is per the Texas Instruments space production baseline and is in compliance with the Texas Instruments Quality Control
System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room temperature
only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not warranted. Visual
Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
