TPS7H5001-SP WCA Model Specification

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:

    gmeaError amplifier transconductance
    COMP to CS_ILIM ratio (CCSR)Power stage transconductance
    VREFReference voltage
