Part Number : RT8800
Function : General Purpose 2/3-Phase PWM Controller for High-density Power Supply
Package : Small 16-Lead VQFN Type
Maker : Richtek Technology
Pinouts : 
Description :
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.
Features
1. 5V Power Supply Voltage
2. 2/3-Phase Power Conversion with Automatic Phase Selection (RT8800 : 2/3-Phase, RT8800B : 2-Phase)
3. Output Voltage Controlled by External ReferenceVoltage
4. Precise Core Voltage Regulation
5. Power Stage Thermal Balance by DCR Current Sensing
