This document provides the register bit values for the one-time programmable (OTP) bits of the orderable part number LP875610BRNFRQ1.
All trademarks are the property of their respective owners.
This technical reference manual can be used as a reference for the LP875610B-Q1 default register bits after OTP memory download. This technical reference manual does not provide information about the electrical characteristics, external components, package, or the functionality of the device. For this information and the full register map, refer to the LP8756x-Q1 Four-Phase 16-A Buck Converter With Integrated Switches data sheet.
Table 1-1 lists the main OTP settings for power rails. Table 2-1 lists the register bits loaded from OTP memory.
