PN8145T Ultra Low Standby Power AC/DC Conversion Chip IC

DatasheetHigh Performance Synchronous Rectification Converter with IntegratedPower MOSFET--PN8145T1 General DescriptionPN8145T is internally integrated with PWM controllers and power MOSFET, dedicated to high performance and peripheral components with streamlined AC / DC switching power supplies. this Chip provides extremely comprehensive and excellent performance of intelligent protection functions, including periodic overcurrent protection (external adjustable), overload protection, over-voltage protection, CS short Road protection, soft start function. Through Hi-mode, Eco-mode, Burst-mode three pulse power regulation mode mixing technology and special device low power structure The technology achieves ultra-low standby power consumption and the best efficiency under full voltage range. The good EMI performance is fully guaranteed by frequency modulation technology and Soft Driver technology. The chip is also equipped with intelligent high voltage boot module. PN8145T provides an advanced implementation of a cost-effective flyback switching power supply system that requires ultra low standby power consumption Platform, very suitable for smart meters, Eur2.0, energy star applications.2 FeaturesMOSFET - 1000V high power built-in avalanche capability- Hi-mode (60kHz PWM)- Eco-mode (dynamic PFM)- Burst-mode (intermittent 25kHz mode)- improve the frequency modulation technology EMI- standby power < 75 mW @230VAC- soft start technology- internal high voltage startup circuit- built-in line voltage compensation and slope compensation- excellent comprehensive protection functionOver temperature protection (OTP)Overload protection (OLP)External resistance adjustable periodic overcurrent protection (OCP)Overvoltage protection (OVP)Short circuit protection for CS3 ApplicationsIn the switching power supply adapter and battery charger In the white goods, personal computer, audio and other auxiliary power supply  smart meters 4 Package/Order Information5 Typical CircuitWhy choose us?* Specilaze in IC for around 14 years  * 100% Tested before sale * Cooperate with over 35 famous brands from domestic and international market * Competitive and reasonable price  * Abundant inventory and short lead time * 24hrs supports from our sales and R&D team   Warranty1 YearLead time3-7 DaysNotes1.The pictures are taken by camera. 2.You can contact us for a better price. 3.Feel free to contact us if you would like to see other models.
