LM2853 October 2006 3A LM2853 550 3A 550 kHz Synchronous SIMPLE SWITCHER® BuckRegulator kHz General Description Features Synchronous The LM2853 synchronous SIMPLE SWITCHER® buck regu- n Input voltage range of 3.0V to 5.5V lator is a 550 kHz step-down switching voltage regulator n Factory EEPROM set output voltages from 0.8V to 3.3V capable of driving up to a 3A load with excellent line and load in 100 mV increments regulation. The LM2853 accepts an input voltage between n Maximum load current of 3A 3.0V and 5.5V and delivers a customizable output voltage n Voltage Mode Control that is factory programmable from 0.8V to 3.3V in 100mV n Internal type-three compensation increments. Internal type-three compensation enables a low n Switching frequency of 550 kHz component count solution and greatly simplifies externalcomponent selection. The exposed-pad TSSOP-14 package n Low standby current of 12 µA enhances the thermal performance of the LM2853. n Internal 40 m MOSFET switches SIMPLE n Standard voltage options 0.8/1.0/1.2/1.5/1.8/2.5/3.0/3.3 volts n Exposed pad TSSOP-14 package Applicationsn Low voltage point of load regulation SWITCHER n Local solution for FPGA/DSP/ASIC core power n Broadband networking and communications infrastructure Typical Application Circuit ®Buck Regulator 20201502 Efficiency vs Load Current (V = 3.3V) OUT 20201501 SIMPLE SWITCHER® is a Registered Trademark of National Semiconductor Corporation. © 2006 National Semiconductor Corporation DS202015 www.national.com Connection Diagram LM2853 20201503 Ordering Information Voltage
