DESCRIPTION
RS2320 is especially designed for non-isolated LED driver. The building in perfect current compensation function ensures the accurate output current. RS2320 has very less external components because of high integrated and simple topology. Thanks to novel power supply, RS2320 need not use transformer and it could simplify PCB design. RS2320 integrates frequency jittering, cycle-by-cycle current limit, inductor anti-saturation and thermal shutdown circuitry onto a monolithic IC.
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-Isolated 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 jittering 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
