Distinctive features
· Operates from universal mains input 85VAC – AC 276V
· High level of integration leads to a very low external component count
· Soft (re)Start to prevent audible noise (externally adjustable)
· Leading Edge Blanking (LEB) for current sense noise immunity
· Mains dependent operation enabling level (Mlevel) (externally adjustable)
Green features
· On-chip start-up current source, which is switched “off” after start-up to reduce the power consumption
· Valley (zero/low voltage) switching for minimal switching losses
· Frequency Reduction at low output powers for improved system efficiency (power consumption < 1W)
· Burst mode operation (Automatic Controlled Burst Mode) for extreme low, no load power levels
Protection features
· Safe-Restart mode for system fault conditions
· Under Voltage Protection (UVLO) for foldback during overload
· Continuous mode protection by means of demagnetization detection
· Accurate Over Voltage Protection (OVP) (external adjustable)
· Cycle-by cycle Over Current Protection (OCP)
· Input voltage independent Over Power Protection (OPP)
· Short Winding Protection (SWP)
· Maximum Ton Protection
· Over Temperature Protection (OTP)
