LM2852 October 2006 2A LM2852 500/1500kHz 2A 500/1500kHz Synchronous SIMPLE SWITCHER® BuckRegulatorGeneral Description Features The LM2852 SIMPLE SWITCHER® synchronous buck regu- n Input voltage range of 2.85 to 5.5V lator is a high frequency step-down switching voltage regu- n Factory EEPROM set output voltages from 0.8V to 3.3V lator capable of driving up to a 2A load with excellent line and in 100mV increments Synchronous load regulation. The LM2852 can accept an input voltage n Maximum load current of 2A between 2.85V and 5.5V and deliver an output voltage that is n Voltage Mode Control factory programmable from 0.8V to 3.3V in 100mV incre- n Internal type-three compensation ments. The LM2852 is available with a choice of two switch- n Switching frequency of 500kHz or 1.5MHz ing frequencies - 500kHz (LM2852Y) or 1.5MHz (LM2852X).It also features internal, type-three compensation to deliver a n Low standby current of 10µA low component count solution. The exposed-pad TSSOP-14 n Internal 60 m MOSFET switches package enhances the thermal performance of the LM2852. n Standard voltage options 0.8/1.0/1.2/1.5/1.8/2.5/3.3 volts Applications SIMPLE n Low voltage point of load regulation n Local solution for FPGA/DSP/ASIC core power n Broadband networking and communications infrastructure n Portable computing SWITCHER Typical Application Circuit ®Buck Regulator 20127001 20127002 SIMPLE SWITCHER®SIMPLE SWITCHERreg; is a registered trademark of National Semiconductor Corporation © 2006 National Semiconductor Corporation DS201270 www.national.com Connection Diagram LM2852 TOP VIEW 20127003 MXA14A ETSSOP-14 Pin Descriptions NC (Pins 5, 12 and 13): No connect.
