AM437x Discrete Power Reference Design (TIDEP0020)

The Sitara AM437x simplified power sequence feature provides flexibility to power designers. This reference design implementation is a BOM-optimized discrete power solution for the AM437x processor with a minimal number of discrete ICs and basic feature set. The solution represents a baseline of a discrete power solution that can be extended for additional features and capabilities of the AM437x processor.

Возможности

Simplified, BOM-optimized discrete power solution for the Sitara AM437x processor. AM437x includes an integrated LDO that simplifies processor power sequencing requirements. Systems without controlled power down can greatly benefit from this feature since the integrated LDO always ensures power up/down sequencing is met for VDDS and VDDSHVx supplies The TLV62565 step down converter provides the 3.3 volt supply and the TLV62080 provides the 1.1 volt supply. Two TLV702xx low drop out regulators (LDOs) provide the 1.5-V and 1.8-V supplies. TLV803M voltage supervisor keeps the processor in reset until all rails are operational and to reset the processor when input power is lost. This design is tested and includes schematics, BOM, design guide, and test data.
