LM2852  
2A 500/1500kHz SIMPLE SYNCHRONOUS Buck  
Regulator  
General Description  
Features  
n Input voltage range of 2.85 to 5.5V  
n Factory EEPROM set output voltages from 0.8V to 3.3V  
in 100mV increments  
The LM2852 SIMPLE SYNCHRONOUS buck regulator is  
a high frequency step-down switching voltage regulator ca-  
pable of driving up to a 2A load with excellent line and load  
regulation. The LM2852 can accept an input voltage be-  
tween 2.85V and 5.5V and deliver a customizable 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 compensation to deliver  
n Maximum Load Current of 2A  
n Voltage Mode Control  
n Internal type three compensation  
n Switching frequency of 500kHz or 1.5MHz  
n Low standby current of 10µA  
n Internal 60 mMOSFET switches  
n Standard voltage options 1.0/1.2/1.5/1.8/2.5/3.3 volts  
a
low component count solution. The exposed-pad  
TSSOP-14 package enhances the thermal performance of  
the LM2852.  
Applications  
n Low voltage point of load regulators  
n Local solution for FPGA/DSP/ASIC core power  
n Broadband networking and communications  
infrastructure  
n Portable computing
