Product Highlights
Lower System Cost, Higher Design Flexibility
● Multi-mode operation maximizes efficiency at all loads
● No heatsink required up to 35 W using P, Gand M packages with universal input voltage and up to 48 W at 230 VAC
● Output over voltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
● Allows both primary and secondary sensing
● Line under voltage (UV) detection prevents turn-off glitches
● Line over voltage (OV) shutdown extends line surge limit
- Accurate programmable current limit
● Optimized line feed-forward for line ripple rejection
● 132 kHz frequency (Y package) reduces transformer and power supply size
● Half frequency option in Y package for video applications
● Tight l2f 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 minimum 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
● Energy efficient over entire load range
● No-load consumption <200 mW at 265 VAC
● Standby power for 1 W input
- >600 mW output at 110 VAC input
- >500 mW output at 265 VAC input

The TOP258YN integrated circuit is a high-performance, off-line, fixed-frequency current-mode PWM controller designed for high-power switch-mode power supplies. It features a wide range of protection functions, including over-voltage protection, over-current protection, and short-circuit protection. It also has a high-precision current-mode control loop, which ensures excellent line and load regul
