1.8A Step-Down Regulator with  
Remote Sense in 2mm x 2mm WLP  
/MX8649A  
General Description  
Features  
o 1.8A Guaranteed Output Current  
The MAX8649/MAX8649A high-efficiency DC-to-DC step-  
down switching regulators deliver up to 1.8A of output cur-  
rent. The device operates from a 2.5V to 5.5V input  
voltage range, making it future proof for next-generation  
battery technologies. The output voltage is I2C program-  
mable from 0.75V to 1.38V. Remote sense ensures pre-  
cise DC regulation at the load. Total output error is less  
than 2% over load, line, and temperature.

Steps)  
o Operates from 2.5V to 5.5V Input Supply  
o On-Chip FET and Synchronous Rectifier  
o Fixed 3.25MHz PWM Switching Frequency  
o Synchronizes to 13MHz, 19.2MHz, or 26MHz  
System Clock when Available  
o Small 1.0µH Inductor  
The ICs operate at a 3.25MHz fixed frequency. The high  
operating frequency minimizes the size of external com-  
ponents. The switching frequency of the converter can be  
synchronized to the master clock of the application. When  
synchronizing to an external clock, the ICs measure the  
frequency of the external clock to ensure that the clock is  
stable before changing the switching frequency to the  
external clock frequency.  
o Initial Accuracy 0.5% at 1.25V Output  
o 2% Output Accuracy Over Load, Line, and  
Temperature  
o Power-Save Mode Increases Light Load Efficiency  
o Overvoltage and Overcurrent Protection  
o Thermal Shutdown Protection  
An on-board DAC allows adjustment of the output volt-  
age in 10mV steps. The output voltage can be pro-  
grammed directly through the I2C interface, or by  
preloading a set of on-board registers and using the  
two VID logic signals to select the appropriate register.  
Other features include internal soft-start control circuitry  
to reduce inrush current, output overvoltage, overcur-  
rent, and overtemperature protection.
