Product Highlights

EcoSmart – Energy Efficient
• Ideal for applications from 10 W to 245 W
• Energy efficient over entire load range
• No-load consumption below 100 mW at 265 VAC
• 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
• 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 start-up stress
• 725 V rated MOSFET
• Simplifies meeting design derating requirements
Extensive Protection Features
• Auto-restart limits power delivery to <3% during overload faults
• Output short-circuit protection (SCP)
• Output over-current protection (OCP)
• Output overload protection (OPP)
