The ICE2QS03G is a quasi-resonant PWM Controller optimized for off-line switch power supply. The digital frequency reduction with decreasing load enables a quasi-resonant operation till very low load. As a result, the overall system efficiency is significantly improved compared to other conventional solutions. The active burst mode operation enables ultra-low power consumption at standby mode with small and controllable output voltage ripple. Based on the BiCMOS technology, the product has a wide operation range (up to 25V) of IC power supply and lower power consumption. The numerous protection functions give a full protection of the power supply system in failure situations. All of these make the ICE2QS03G an outstanding controller for quasi resonant flyback converter in the market.
  • Active burst mode for low standby power
  • Quasi resonant operation
  • Digital frequency reduction for better overall system efficiency
  • Quasi resonant operation till very low load
  • Active burst mode operation at light/no load for low standby input power (<100mW)
  • Digital frequency reduction with decreasing load
  • Startup cell for VCC pre-charging with constant current
  • Built-in digital soft-start
  • Foldback correction and cycle-by-cycle peak current limitation
  • Latch-off mode for adjustable output over-voltage protection and short-winding protection

Applications

Consumer Electronics, Communications & Networking, Power Management, Audio

Not fur Surfing or other Water Sports
I got this in a swag bag from a surfing contest. The stick is very dry...that's the only way I can explain how it feels. It certainly doesn't glide on like other face sticks. After one wave and ducking my face in the water, the product smeared off and ran into my eyes. My vision got blurry from that, and it was really hard to see the waves coming in. I won't be using this product ever again. I also looked at the EWG website, and this product was given a 6. For those new to EWG, that's not a good rating. You want like a 1 or 2.

Too little product for the price
I was surprised at how little product you get for the price. After only two weeks, the bar already broke in half, and there's not much left. Additionally, it leaves white streaks, so you'll need to rub it in after applying. I still like the fact that it's got clean organic ingredients. I won't by the bar again, but I will try the spray
