500V Startup Cell switched off after Start Up
The ICE3BS03LJG 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,
Active Burst Mode for lowest Standby Power
Fast load jump response in Active Burst Mode
65kHz internally fixed switching frequency
Built-in Latched Off Protection Mode for
Overtemperature, Overvoltage & Short Winding
•
Auto Restart Protection Mode for Overload, Open Blue Ray DVD player and recorder, set top box, charger,
Loop & VCC Undervoltage
Built-in Soft Start
note book adapter, etc. The inherited outstanding features
includes 500V startup cell, active burst mode (achieve the

Vin=270Vac) 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 26V),

Overall tolerance of Current Limiting < ±5%
Internal PWM Leading Edge Blanking
BiCMOS technology provide wide VCC range
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, ICE3BS03LJG is a
versatile PWM controller for low to medium power
application.
