1 / 13 page LM2852 2A 500/1500kHz SIMPLE SYNCHRONOUS™ Buck Regulator General Description 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 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 1.0/1.2/1.5/1.8/2.5/3.3 volts 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 Typical Application Circuit 20127001 20127002 January 2005 © 2005 National Semiconductor Corporation DS201270 www.national.com |
