Off-Line SMPS Current Mode Controller With Integrated 500V Startup Cell ( Latched And Frequency Jitter Mode )

The ICE3AS03LJG is the latest version of the F3 controller for lowest standby power and low EMI features with both auto-restart and latch off protection features to enhance the system robustness. It targets for off-Line battery adapters, and low cost SMPS for low to medium power range such as application for the DVD R/W, DVD Combi, Blue Ray DVD player and recorder, set top box, charger, note book adapter, etc. The inherited outstanding features includes 500V startup cell, active burst mode (achieve the lowest standby power; i.e. <100mV at no load with Vin=265Vac) and propagation delay compensation (accurate output power limit for wide range input), modulated Gate drive (low EMI), etc. The newly added technology and features CAN further enhance the features. It includes BiCMOS technology (further lower power consumption and extend Vcc operating range to 25V), frequency jittering feature (low EMI), built-in soft start, built-in blanking window with extendable blanking time for high load jump, external latch off enable pin (feasible for extra protection), etc. Therefore, ICE3AS03LJG is a versatile PWM Controller for low to medium power application.
