ICE5AR4770BZS1XKLA1

ICE5AR4770BZS1XKLA1 is a 5th generation of fixed frequency integrated power IC (CoolSET™) optimized for an off-line switch mode power supply in cascode configuration. The cascode configuration helps achieve fast start-up. The frequency reduction with soft gate driving and frequency jitter operation offers lower EMI and better efficiency between light load and 50% load. The selectable entry and exit standby power ABM enable flexibility and ultra-low power consumption in standby mode with a small and controllable output voltage ripple. The product has a wide operating range (10.0 ~ 25.5V) of IC power supply and lower power consumption. The numerous protection functions support the power supply system in failure situations. Applications include auxiliary power supply for home appliances/white goods, TV, PC and server, Blu-ray player, set-top box and LCD/LED monitor.
