Here is the English information on the FAN65004B chip:

The FAN65004B is a low voltage buck-boost voltage regulator from Texas Instruments.

Key Specifications:

• Input voltage range: 2.7V to 5.5V
• Output voltage: Fixed, adjustable 3.3V
• Maximum load current: 1A
• Buck-boost conversion efficiency up to 90%
• Small 4mm x 4mm QFN package

This step-up/step-down DC-DC converter provides a stable 3.3V output from a wide input range of 2.7V to 5.5V.

It uses an integrated high-side and low-side MOSFET to enable buck-boost conversion with minimal external components.

Up to 1A continuous output current handling capability.

Tiny 4mm x 4mm QFN package maximizes board space efficiency.

Ideal for battery-powered devices requiring voltage regulation near the limits of a single cell battery.

Well-suited for wearables, portable gadgets, sensors and other applications operating below 1A load.

In summary, the FAN65004B offers an easy-to-use ultra-small buck-boost converter in a compact QFN package.
