The LP87524B/J/P-Q1 contains four step-down DC/DC converter cores, which are configured as 4 single phase outputs. These devices power AWR1642 and AWR1243 automotive radar devices and IWR1642 industrial radar devices.

This technical reference manual can be used as a reference for the LP87524B/J/P-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 LP87524B/J/P-Q1 Four 4-MHz Buck Converters for AWR and IWR MMICs datasheet.

There are a few important connections to ensure the LP87524B/J/P-Q1 is configured correctly, each of which are described in this section. Good examples of how to connect the radar devices to the LP87524B/J/P-Q1 PMICs are shown in Figure 2-1, Figure 2-2 and Figure 2-3. LDOs are not required as the device meets noise and ripple specifications with LC filters. Refer to XWR1xxx Power Management Optimizations – Low Cost LC Filter Solution application report.
