3 Description
The TPS7H4001-SP is a radiation-hardness-assured,
7-V, 18-A synchronous buck converter with integrated
low-resistance high-side and low-side MOSFETs.
High efficiency and reduced component count are
achieved through current mode control.
The output voltage start-up 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 possible by correctly configuring the
enable and the power good pins. The TPS7H4001-SP
can be configured in primary-secondary mode and
with the SYNC2 pin, four devices can be configured in
parallel without an external clock.
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 protection
which prevents current runaway. Thermal shutdown
disables the part when die temperature exceeds
thermal limit.
