National Semi Intros SIMPLE SYNCHRONOUS Regulator
National Semiconductor Corp. (Santa Clara, CA) introduced the LM2852, the first member of its new, high-efficiency SIMPLE SYNCHRONOUS™ buck regulator family. This low-voltage, high-performance switching regulator is highly integrated for low component count, making it suitable for use in cable and xDSL modems, digital signal processors, field-programmable gate arrays and set-top boxes.
The SIMPLE SYNCHRONOUS family builds on the system deployment of National’s SIMPLE SWITCHER® portfolio of converters. National will expand this family throughout 2005 with additional SIMPLE SYNCHRONOUS regulators with the same input–output voltage range and output currents from 1 A to 3 A.
The LM2852 is a synchronous, high-frequency step-down switching voltage regulator capable of driving up to a 2 A load with line and load regulation. The LM2852 can accept an input voltage between 2.7 V and 5.5 V and deliver a customizable output voltage that is factory-programmable from 0.8 V to 3.3 V in 100 mV increments. The LM2852 is available with a choice of two switching frequencies, 500 kHz and 1.5 MHz. The LM2852 is available for simulation on National’s WEBENCH design tool.
The LM2852, offered in a thermally enhanced TSSOP-14 package, is priced at $2.50 each in 1,000-unit quantities.
