RT8800 datasheet



The RT8800, RT8800B are general purpose multi-phase synchronous buck controllers dedicating for high density power supply regulation.

The parts implement 2, and 3 buck switching stages operating in interleaved phase set automatically. The output voltage is regulated and controlled following the input voltage of FB pin.

With such a single analog control, the RT8800/B provide a simple, flexible, wide-range and extreme cost-effective high density voltage regulation solutions for various high-density power supply application.


1. Output Voltage Controlled by External Reference Voltage

2. Precise Core Voltage Regulation

3. Power Stage Thermal Balance by DCR Current Sensing

4. Extreme Low-Cost, Lossless Time Sharing Current Sensing

5. Internal Soft-start

6. Hiccup Mode Over-Current Protection



1. Desktop CPU core power

2. Low Output Voltage, High power density DC-DC

3. Converters

4. Voltage Regulator Modules
