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.

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.
