The TPS56221 is a high-efficiency synchronous switcher with integrated FETs, which achieves a power density of greater than 200W/in3 with greater than 90 percent efficiency at high loads. The easy-to-use SWIFT step-down regulator supports 25-A point-of-load designs for telecommunications, networking and other applications.

Features:

• Three selectable frequencies: 300kHz, 500kHz, 1MHz
• Easy-to-design 5x6-mm QFN PowerPAD™ delivers 200W/in3
• >90% efficiency over load
• Integrated high and low MOSFETs

Benefits:

• Design flexibility for highest efficiency, smallest size or a balance of both
• 30% smaller package than competitive 12-V, 25-A integrated inductor solutions
• Low thermal resistance delivers full 25-A rated current without airflow
• High performance, ease of design
