FEATURES•LM27313-Q1 is an Automotive Grade Productthat is AEC-Q100 Grade 1 Qualified (-40°C to+125°C Operating Junction Temperature)30V DMOS FET Switch1.6 MHz Switching FrequencyLow RDS(ON) DMOS FETSwitch Current up to 800 mAWide Input Voltage Range (2.7V–14V)Low Shutdown Current (<1 μA)5-Lead SOT-23 PackageUses Tiny Capacitors and InductorsCycle-by-Cycle Current LimitingInternally CompensatedDESCRIPTIONThe LM27313 switching regulator is a current-modeboost converter with a fixed operating frequency of1.6 MHz.The use of the SOT-23 package, made possible bythe minimal losses of the 800 mA switch, and smallinductors and capacitors result in extremely highpower density. The 30V internal switch makes thesesolutions perfect for boosting to voltages of 5V to28V.This part has a logic-level shutdown pin that can beused to reduce quiescent current and extend batterylife.Protection is provided through cycle-by-cycle currentlimiting and thermal shutdown. Internal compensationsimplifies design and reduces component count.2••••••••••APPLICATIONS•••••White LED Current SourcePDA’s and Palm-Top ComputersDigital CamerasPortable Phones, Games and Media PlayersGPS Devices 全新原装正品公司现货
