Special Purpose Regulators Procurement Notes

Verify the specific suffix RSLR against the official datasheet to confirm reel packaging and moisture sensitivity level requirements. Ensure compatibility with the target PCB footprint for the VQFN-48 package. Confirm that the design accounts for the specified operating temperature range and input voltage constraints before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component when a dual-output solution with high current capability is required for CPU or GPU loads. The integrated D-CAP+ technology reduces external compensation components compared to traditional voltage mode controllers. Consider the PMBus interface if telemetry and remote configuration are necessary for system monitoring and optimization during operation.

Special Purpose Regulators Part Context

This part belongs to the TPS536C series of multiphase controllers, which utilize Texas Instruments' D-CAP+ control scheme.
