The FAN6921MLMY from Infineon Technologies is a synchronous buck DC-DC controller capable of driving external MOSFETs to deliver up to 1.5A of regulated output current.

Key Features:

• Integrated high/low side drivers rated for 1.5A continuous output
• Wide 4.5V to 15V input voltage operating range
• Controls external MOSFETs for adjustable 0.6V to 5.5V regulation
• Small Mini SOIC8 package optimized for space constrained boards
• Internal fixed 1.2MHz switching frequency

Common Applications:

• Point-of-load regulation for dense board designs
• Primary supply for miniature/low power embedded devices
• Space critical distributed power systems up to 1.5A

Benefits Include:

• Allows flexibility with varying 4.5-15V input sources
• Simplifies component selection for integrated 1.5A solution
• Enables highly compact controller solution in ultra-small footprint

Well-suited for applications requiring up to 1.5A output where board area is extremely limited.

In summary, the FAN6921MLMY offers leading 1.5A control capability optimized for minimal size.
