Texas Instruments TPS56C215 Synchronous Step-Down SWIFT Converter
Texas Instruments TPS56C215 Synchronous Step-Down SWIFT™ Converter is a small-sized, synchronous buck converter with an adaptive on-time D-CAP3™ control mode. The device offers ease-of-use and low bill-of-material count for space-conscious power systems. The Texas Instruments TPS56C215 features high-performance, low RDSon integrated MOSFETs, accurate 0.6V reference, and an integrated boost switch. Competitive features include very-low external-component count, fast load transient response, auto-skip mode operation, internal soft-start control, and no requirement for external compensation. A forced continuous conduction mode helps meet tight voltage regulation accuracy requirements for performance DSPs and FPGAs.
Features
- Integrated 13.5mΩ and 4.5mΩ MOSFETs
- Support 12A continuous IOUT
- 0.6V +/-1% reference voltage across the entire temperature range
- 0.6V to 5.5V output voltage range
