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.
