Product Introduction
Converter Offline Flyback Topology 66kHz;;;132kHz TO-220
Features
- Low thermal impedance junction-to-case (2 ℃ per watt)
- Low height is ideal for adapters where space is limited
- Simple mounting using a clip to aid low cost manufacturing
- Horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications
- Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink
- Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
- Allows both primary and secondary sensing
- Line undervoltage (UV) detection prevents turn-off glitches
- Line overvoltage (OV) shutdown extends line surge limit
- Accurate programmable current limit
- Optimized line feed-forward for line ripple rejection
- 132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size
- Half frequency option for video applications
- Frequency jittering reduces EMI filter cost
- Heatsink is connected to SOURCE for low EMI
- Improved auto-restart delivers -3% of maximum power in short circuit and open loop fault conditions
- Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset
- Fully integrated soft-start for minimum start-up stress
- Extended creepage between DRAIN and all other pins improves field reliability
