Description
General part information
TPS7H4001-SP Series
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.
