RT8088A  
2.7MHz 3A Step-Down Converter with I2C Interface  
General Description  
Features  
2.5V to 5.5V Input Voltage Range  
Current Mode COT Control Loop Design  
Fast Transient Response  
The RT8088A is a full featured 5.5V, 3A, Constant-On-  
Time (COT) synchronous step-down converter with two  
integrated MOSFETs. The current mode COT operation  
with internal compensation allows the transient response  
to be optimized over a wide range of loads and output  
capacitors to efficiently reduce external component count.  
The RT8088A provides up to 2.7MHz switching frequency  
to minimize the size of output inductor and capacitors.  
The output voltage is programmed through an I2C interface  
capable of operating up to 400kHz.  
Internal 48mΩ and 22mΩ Synchronous Rectifier  
I2C compatible interface up to 400kHz  
Highly Accurate VOUT Regulation Over Load/Line  
Range  
Robust Loop Stability with Low-ESR COUT  
RoHS Compliant and Halogen Free  
Applications  
Distributed Power Systems  
The RT8088Ais available in the WL-CSP-15B 1.31x2.11  
(BSC) package.  
Enterprise Servers, Ethernet Switches & Routers, and  
Global Storage Equipment
