3BS3LJ ICE3BS03LJG SOP8

Description
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,
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=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),
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.
