FAN3278TMX onsemi / Fairchild

Here is the English information on the FAN3278TMX chip:

The FAN3278TMX is a synchronous step-down (buck) DC-DC converter from Infineon Technologies.

Key specifications:

• Input voltage range: 4.5V to 40V
• Output voltage range: 0.6V to 16V
• Maximum output current: 3A
• Integrated high/low side MOSFETs
• Switching frequency up to 2MHz
• Protection against overvoltage, overcurrent, overtemperature
• Available in 6x6mm QFN package

The FAN3278TMX utilizes an integrated dual MOSFET architecture to efficiently step down the wide input voltage range.

Comprehensive protections ensure safe operation under fault conditions.

Capable of delivering up to 3A of output current across a broad voltage range, this makes an ideal general purpose buck converter.

The QFN package provides excellent thermal performance for higher power applications.

In summary, the FAN3278TMX is a robust 3A synchronous buck regulator suitable for general purpose applications requiring an efficient and reliable solution from a single high-power DC source.
