3 Description
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.
