FEATURES |
| • Multi-mode operation maximizes efficiency at all loads |
| • No heatsink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC |
| • 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 |
| • 132 kHz frequency (Y package) reduces transformer and power supply size |
| • Half frequency option in Y package for video applications |
| • Tight I2f parameter tolerance reduces system cost |
| ° Maximizes MOSFET and transformer power delivery |
| ° Minimizes overload power, reducing cost of transformer, primary clamp and secondary components |
| • Frequency jittering reduces EMI filter cost |
| • 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 mimimum start-up stress |
| • Pin-out simplifies heatsinking to the PCB for P,G and M packages |
| • Extended creepage between DRAIN and all other pins improves field reliability |
| • Heatsink is connected to SOURCE for low EMI |
