1 / 14 page LM2852 2A 500/1500kHz Synchronous SIMPLE SWITCHER® Buck Regulator General Description The LM2852 SIMPLE SWITCHER® synchronous buck regu- lator is a high frequency step-down switching voltage regu- lator 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 incre- ments. The LM2852 is available with a choice of two switch- ing frequencies - 500kHz (LM2852Y) or 1.5MHz (LM2852X). It also features internal, type-three compensation to deliver a low component count solution. The exposed-pad TSSOP-14 package enhances the thermal performance of the LM2852. 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 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 m Ω MOSFET switches n Standard voltage options 0.8/1.0/1.2/1.5/1.8/2.5/3.3 volts Applications 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 Typical Application Circuit 20127001 20127002 SIMPLE SWITCHER® SIMPLE SWITCHERreg; is a registered trademark of National Semiconductor Corporation October 2006 © 2006 National Semiconductor Corporation DS201270 www.national.com |
