PI TOP258PN TOP258 DIP-8C TOPSwitch-HX Enhanced EcoSmart Integrated Off-Line Switcher
Description:
TOP258PN TOP258 is one of TOPSwitch-HX family. TOPSwitch-HX cost effectively incorporates a 700V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
Features:
Multi-mode operation maximizes effi ciency at all loads
New eSIP-7F and eSIP-7C packages
- Low thermal impedance junction-to-case (2 °C 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
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
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 fi lter cost
Heatsink is connected to SOURCE for low EMI
Improved auto-restart delivers
