State-of-the-art power control IC's for power ranges up to 300 W with innovative protection features for superior safety and reliability in operation.
The new ICE2QS0X is a high performance current mode  controllers for the SMPS applications such as LCD/PDP TV, color TV, DVD, adapters, Set-Top-Boxes for Satellite and Cable services etc.

Of special note are its frequency modulation, its ultra low standby power consumption and an extensive array of protection features, allowing low EMI and highly efficient, reliable and cost effective designs.

There are 2 version of controller; with startup cell (ICE2QS01 andICE2QS03) and without startup cell (ICE2QS02).  ICE2QS01/3 are implemented with active bust mode and is the best-in-class of standby power performance. The ICE2QS02 is good for main converter where the auxiliary power is provided. It has implemented with extra protection features such as brownout, adjustable blanking time for OLP,etc to suit for system requirement

ICE2QS0X Features

  • 500V startup cell for IC self power supply during various states (ICE2QS01/3)

  • Digital frequency reduction with decreasing load for higher efficiency

  • Active Burst Mode Operation for ultra-low standby power (<1W@0.5W load) (ICE2QS01/3)

  • Cycle by cylce peak current limitation

  • Extensive Protection features to protect the IC and the system from various fault conditions

  • Brownout, adjustable blanking time for OLP (ICE2QS02)
