TOP257GN-TL Datasheet PDF - Power Integrations

● Multi-mode operation maximizes efficiency 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 heat sink 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 filter cost
