深圳原装现货 RS2320 普诚LED驱动器芯片
FEATURES
● High efficiency (Reach 90%)
● High precision output current regulation (-3%~+3%) when universal AC input voltage (85VAC~265VAC)
● Lowest cost and very less component count solution
● Non-lsolated Buck application
● Need not transformer to simplify design
● Operation in CCM
● Support no electrolytic capacitor
● Programmable output current setting
● 50KHz operation frequency allows low cost 1mH inductor for up to 30V & 300mA output current
● Tight tolerances and negligible temperature variation
● Frequency jttering dramatically reduces EMI, minimizes EMI filter cost
● Under voltage lockout (9.0V~15V)
● Low startup current (<20μA)
● Building in current compensation
● Building in 400nS LEB time for CS pin
● Audio noise free operation
● SOT-23-6L Pb free package
APPLICATIONS
● Cell Phone Charger
● Small Power Adaptor
● Non-isolated LED driver
● Industrial Controls
