■Description of Change:
●This notice is to advise our customers of a minor, design revision for the Intersil ISL9238* products. The change doubles the programmable range of the phase comparator threshold offset in both the forward and reverse Buck and Buck-Boost modes. The LSB weight was doubled, thereby increasing both the step size and overall range.
●Products impacted by the change are: ISL9238HRTZ, ISL9238HRTZ-T7A, ISL9238HRTZ-TKS2568, ISL9238IRTZ-T
ISL9238HRTZ-T, ISL9238HRTZ-TK, ISL9238IRTZ
■Reason for Change:
●The change improves the detectability of when the phase node crosses through 0V. This improves the light load efficiency of the part. Please refer Appendix A for details.
■Product Identification:
●There will be no change in the external marking of the packaged parts. Product affected by this change is identifiable via Intersil’s internal traceability system and a register that can be used to identify revision of the product (see appendix A for details). Revision 2 material is effective date code 1732.
■Impact on fit, form, function, quality & reliability:
●The change will have no impact on the form, fit, function, quality, reliability and environmental compliance of the devices. Both the old and new versions have no impact to customer designs using the default setting (000 = 0mV).
