Unique DC/DC converter combines true fixed frequency and ultra-fast transient
Texas Instruments (TI) has introduced the industry’s first 16-V input, 40-A synchronous DC/DC buck converter with an internally compensated advanced-current-mode (ACM) control topology supporting frequency synchronization. TI’s TPS543C20 SWIFT converter provides enhanced efficiency by integrating its latest generation of low resistance high- and low-side MOSFETs into a thermally efficient small-footprint package. Designers can stack two converters side by side to drive loads up to 80 A for processors in space-constrained and power-dense applications in various markets, including wired and wireless communications, enterprise and cloud computing, and data storage systems.
TPS543C20 key features and benefits
- Provides greater than 90 percent efficiency at a 40-A peak-load current.
- Maintains 0.5 percent reference-voltage accuracy over temperature and full differential remote-voltage sensing to meet the voltage-accuracy requirements of deep submicron processors.
- Provides up to 80 A at point-of-load when stacking two converters.
- Offers very high power density and the PowerStack quad flat no-leads (QFN) package enables easy heat sinking from the single ground pad.
