Features
Description
• 500V Startup Cell switched off after Start Up
The ICE3AS03LJG is the latest version of the F3 controller
• Active Burst Mode for lowest Standby Power
for lowest standby power and low EMI features with both
• Fast load jump response in Active Burst Mode auto-restart and latch off protection features to enhance
• 100kHz internally fixed switching frequency
the system robustness. It targets for off-Line battery
• Built-in Latched Off Protection Mode for
adapters, and low cost SMPS for low to medium power
Overtemperature, Overvoltage & Short Winding range such as application for the DVD R/W, DVD Combi,
• Auto Restart Protection Mode for Overload, Open Blue Ray DVD player and recorder, set top box, charger,
Loop,VCC Undervoltage & Short Optocoupler note book adapter, etc. The inherited outstanding features
• Built-in Soft Start
includes 500V startup cell, active burst mode (achieve the
• Built-in blanking window with extendable blanking lowest standby power; i.e. <100mV at no load with
time for short duration high current
Vin=265Vac) and propagation delay compensation
• External latch off enable function
(accurate output power limit for wide range input),
• Max Duty Cycle 75%
modulated gate drive (low EMI), etc. The newly added
• Overall tolerance of Current Limiting < ±5%
technology and features can further enhance the features.
• Internal PWM Leading Edge Blanking
It includes BiCMOS technology (further lower power
• BiCMOS technology provide wide VCC range
consumption and extend Vcc operating range to 25V),
• Frequency jitter and soft gate driving for low EMI 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.
