Advantages
- The best-in-class efficiency over entire load range allows energy saving and simple thermal management
- The common footprint for 2A, 4A, 8A and 12A devices provides design flexibility and allow cut and paste layout.
- The need for traditional dual stage POL conversion is eliminated which saves energy, size and cost by operating directly from 12Vin.
- Excellent package thermal properties and low height allows back-side board mounting for additional space savings.
- The small footprint and high switching frequency allows smaller total solution size and cost.
- The Gen2.1 family is a full featured, high performance compact solution for server, storage and Netcom applications allowing easy on-board implementation for fast time to market.
Gen2.1 Family Improvements
- Added Over Voltage Detection (PGOOD window comparator)
- Shorter dead-time to reduce power loss
- Reduced SYNC FET RDS(on) maximum value for better current limit accuracy
- New current options
