Requirements < 100mW
• Built-in latched Off protection Mode and external latch enable
function to increase robustness of the system
• Built-in and extendable blanking Window for high load jumps to
increase system reliability
• Frequency jitter for low EMI
• Green Mould Compound
• Pb-free lead plating; RoHS compilant

Description
PG-DSO-8
• 500V Startup Cell switched off after Start Up
The ICE3GS03LJG is the 130KHz version of the
• Active Burst Mode for lowest Standby Power
ICE3AS03LJG which is the latest version of the F3
• Fast load jump response in Active Burst Mode controller for lowest standby power and low EMI features
• 130kHz internally fixed switching frequency
with both auto-restart and latch off protection features to
• Built-in Latched Off Protection Mode for
enhance the system robustness. It targets for off-Line
Overtemperature, Overvoltage & Short Winding battery adapters, and low cost SMPS for low to medium
• Auto Restart Protection Mode for Overload, Open power range such as application for the DVD R/W, DVD
Loop,VCC Undervoltage & Short Optocoupler Combi, Blue Ray DVD player and recorder, set top box,
• Built-in Soft Start
charger, note book adapter, etc. The inherited outstanding
• Built-in blanking window with extendable blanking features includes 500V startup cell, active burst mode
time for short duration high current
(achieve the lowest standby power; i.e. <100mV at no load
• External latch off enable function
with Vin=265Vac) and propagation delay compensation
• Max Duty Cycle 75%
(accurate output power limit for wide range input),
• Overall tolerance of Current Limiting < ±5%
modulated gate drive (low EMI), etc. The newly added
• Internal PWM Leading Edge Blanking
technology and features can further enhance the features.
• BiCMOS technology provide wide VCC range It includes BiCMOS technology (further lower power
• Frequency jitter and soft gate driving for low EMI 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, it is a versatile PWM
controller for low to medium power application.
