FEATURES  
DESCRIPTION  
The LM2852 SIMPLE SWITCHER® synchronous  
2
Input Voltage Range of 2.85 to 5.5V  
buck regulator is  
a high frequency step-down  
Factory EEPROM Set Output Voltages from  
0.8V to 3.3V in 100mV Increments  
switching voltage regulator capable of driving up to a  
2A load with excellent line and load regulation. The  
LM2852 can accept an input voltage between 2.85V  
and 5.5V and deliver an output voltage that is factory  
programmable from 0.8V to 3.3V in 100mV  
increments. The LM2852 is available with a choice of  
two switching frequencies - 500kHz (LM2852Y) or  
1.5MHz (LM2852X). It also features internal, type-  
three compensation to deliver a low component count  
solution. The exposed-pad HTSSOP-14 package  
enhances the thermal performance of the LM2852.  
Maximum Load Current of 2A  
Voltage Mode Control  
Internal Type-Three Compensation  
Switching Frequency of 500kHz or 1.5MHz  
Low Standby Current of 10µA  
Internal 60 mMOSFET Switches  
Standard Voltage Options
