Product Highlights
EcoSmart® - Energy Efficient

* Energy efficient over entire load range
* No-load consumption below 70 mW at 230 VAC achievable
* Up to 750 mW standby output power for 1 W input at 230 VAC

High Design Flexibility for Low System Cost

* Multi-mode PWM control maximizes efficiency at all loads
* 132 kHz operation reduces transformer and power supply size
o 66 kHz option for highest efficiency requirements
* Accurate programmable current limit
* Optimized line feed-forward for line ripple rejection
* Frequency jittering reduces EMI filter cost
* Fully integrated soft-start for minimum startup stress
* 725 V rated MOSFET
o Simplifies meeting design derating requirements
