TPS7H5001-SP is the radiation-hardened part
- RHA (radiation hardness assured) to TID 100krad(Si)
- SEL, SEB, and SEGR immune to LET = 75MeVcm2/mg
- SET and SEFI characterised to LET = 75MeVcm2/mg
- No cross-conduction events for controller outputs observed during SET characterisation
- Thermally-enhanced CFP
Both controllers have a pair of anti-phase non-overlapping outputs with controlled dead-time, plus a pair of synchronised outputs to drive synchronous rectifiers – four outputs total for each IC.
For single-ended converter topologies, they allow control over maximum duty cycle.
Other features include: programmable slope compensation, soft-start and programmable leading edge blank time.
Potential applications include high-current buck converters for
FPGA core voltages.
Both of the above are the fully-featured devices in families generically named TPS7H500x-S(E)P product pages:
