FAN7601BMX onsemi / Fairchild

Here is the English description of the FAN7601BMX chip:

• Function: Step-Down DC-DC Converter
• Input Voltage Range: 4.5V to 24V
• Output Voltage: 1.2V/1.5A, 2.5V/1.2A, 3.3V/1A fixed
• Switching Frequency: 650kHz
• Package: SOT-23-5

The FAN7601BMX is a step-down (buck) DC-DC converter from Infineon Technologies.

Key Features:

• Provides three fixed output voltages from a single device
• Wide 4.5V to 24V input operating range
• Miniature SOT-23-5 package saves board space
• Up to 94% efficiency enables low power designs

Common Applications:

• Portable appliances, wearables with multi-rail needs
• Space constrained systems requiring 3.3V/1.2V/2.5V rails
• Quick proven solution when exact voltages are known

Benefits include an integrated high efficiency solution to generate multiple fixed voltages in a tiny package. Reduces design complexity.

Well-suited for cost-sensitive portable devices that require 1.2V, 2.5V and 3.3V rails from a single variable input voltage source.

In summary, the FAN7601BMX is a multi-output buck regulator optimized for generating fixed voltages efficiently in ultra-small footprints.
