AL1788中文资料LOW STANDBY POWER PFC CONTROLLER数据手册Diodes规格书

描述 Description

AL1788 is a high performance AC/DC Power Factor Correction (PFC) controller targeting at LED lighting applications. Based on Primary Side Regulation (PSR) implementation, AL1788 does not require opto-coupler and any secondary feedback circuit to save overall BOM cost. It operates at Quasi-Resonant (QR) mode where MOSFET is turned on at the valley of the drain voltage, which minimizes switching loss to result in high efficiency.

特性 Features

•PSR Implementation Based on Flyback and Buck Topology 
•Universal AC Voltage Input for Constant Voltage (CV) Regulation
•Valley Detection for Primary MOSFET Switch to Achieve Low Switching Loss and High Efficiency
•High PF (>0.9) and Low THD (<20%) for Wide Loading Range (50% to Full Loading)
•Internal Protections: 
•Under-Voltage Lockout (UVLO)
•Over-Voltage Protection (OVP)
•Over-Current Protection (OCP)
•Output Short Protection (OSP)
•Over-Temperature Protection (OTP): Thermal Shutdown and Auto Thermal Recovery
•Low Standby Power 
•Low System BOM Cost 
•Controller with External MOSFET

应用 Application

•General LED Lighting
•Smart Connected LED Light Bulbs
•Smart Connected LED Tubes, Panel Lights, Troffers, and Ceiling Lights
•High PFC and low THD power supply
