SLVUCE8 March 2022 TPS7H5001-SP

The TPS7H5001-SP WCA model takes the TPS7H5001-SP SIMPLIS Model and allows users to edit specific parameters related to the frequency response of a power converter. Monte Carlo analysis can also be performed to observe the distribution of behavior across a specified sample size of devices. The following tests/device characteristics have provided data in order to find worst case conditions for parameters associated with frequency response analysis.

- Process Variation CharacteristicsDevice-to-device manufacturing differences;

Data characteristics provided comes from an internal statistical model of variation due to the manufactering process.

- LDR Radiation Test

Data characteristics provided after devices exposed up to the maximum rated Total Ionizing Dose (TID) of the device: 100 krad at a does rate of XXX rads(Si)/s

- HDR Radiation TestData characteristics provided after devices exposed up to the maximum rated Total Ionizing Dose (TID) of the device: 100 krad at a does rate of 72.28 rads(Si)/s

- Life Test

Data characteristics provided at 25°C after 1,000 hours of testing at 125°C, and meant to emulate 15 years operating at 65-95°C as defined by Group C specifications in MIL-PRF-38535. Additional data provided at -55°C and 125°C for the same devices.

In the model, the specific device parameters influenced by the above variation include:

- gm

- COMP to CS_ILIM ratio (CCSR)Power stage transconductance

- V
