SLVUC26A March 2021 – April 2021 LM53602-Q1 , LM53603-Q1 , LP8733-Q1 , TDA3MA , TDA3MV , TPS22965-Q1 , TPS54116-Q1 , TPS61240-Q1
The OTP settings for the LP8733-Q1 are described in this document.
In addition, power solutions are available using TPS65919-Q1 or TPS65917-Q1 as described in the TPS65919-Q1 and TPS65917-Q1 User's Guide to Power TDA3x. See Table 2-1 to determine the recommended part number based on the DDR memory type and the Vdd_dspeve current requirement of the processor.
Texas Instruments recommends having 15% margin in the load current. Therefore the current requirements listed in Table 2-1 are 15% lower than the maximum capability of the regulator. If the Vdd_dspeve current in the application is unknown, select the TPS65919-Q1 configuration because it supports the maximum performance of the processors. For systems requiring functional safety, the TPS65919-Q1 and TPS65917-Q1 devices comply with applicable ISO 26262 ASIL-B requirements.
