• Integrates dual synchronous buck converters with high switching frequency for compact passive component sizing.
• Includes dual LDOs and a reset supervisor for comprehensive system power sequencing and monitoring.
• Automotive-grade reliability with AEC-Q100 certification for harsh environment operation.

Applications

• Automotive infotainment systems
• Telematics control units
• Body control modules

Procurement Notes

Verify the specific suffix 'V+' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package type matches the required TQFN-EP-20 footprint for PCB layout compatibility. Check current supply chain status as availability may be restricted or limited due to product lifecycle stages.

Selection Notes

Select this component when designing automotive electronics requiring a single-chip solution for multiple voltage rails. Ensure the input voltage does not exceed 28 V. Verify that the thermal performance of the TQFN-20 package meets the application's heat dissipation requirements under maximum load conditions.
