TEA1533集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)規(guī)格書(shū)PDF中文資料

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)
