توضیحات
ICE2QS01 ICE2QS01 DIP8
ICE2QS01 is a quasi-resonant PWM controller
optimized for off-line switch power supply applications
such as LCD TV, CRT TV and notebook adapter. The
digital frequency reduction with decreasing load
enables a quasi-resonant operation till very low load.
As a result, the system efficiency is significantly
improved compared to other conventional solutions.
The active burst mode operation enables an ultra-low
power consumption at standby mode with small and
controllable output voltage ripple. The innovative
power cell solves the IC power supply problem when
the output voltage is pulled down during standby
mode, or during latch-off mode. The numerous
protection functions give a full protection of the power
supply system in failure situations. All of these make
the ICE2QS01 an outstanding controller for quasiresonant flyback converter in the market.
