Product Summary

The TOP256YN is a member of TOPSwitch-HX Family. It is an enhanced ecosmart, integrated off-line switcher with advanced feature set and extended power range. TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.

Parametrics

TOP256YN absolute maximum ratings: (1)DRAIN Peak Voltage: -0.3 V to 700 V; (2)DRAIN Peak Current: TOP256: 4.08 A; (3)CONTROL Voltage: -0.3 V to 9 V; (4)control Current: 100 mA; (5)VOLTAGE MONITOR Pin Voltage: -0.3 V to 9 V; (6)CURRENT LIMIT Pin Voltage: -0.3 V to 4.5 V; (7)MULTI-FUNCTION Pin Voltage: -0.3 V to 9 V; (8)FREQUENCY Pin Voltage: -0.3 V to 9 V; (9)Storage Temperature: -65 ℃ to 150 ℃; (10)Operating Junction Temperature: -40 ℃ to 150 ℃; (11)Lead Temperature: 260 ℃.

Features

TOP256YN features: (1)Multi-mode operation maximizes effi ciency at all loads; (2)New eSIP-7F and eSIP-7C packages; (3)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; (4)Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset; (5)Line undervoltage (UV) detection prevents turn-off glitches; (6)Line overvoltage (OV) shutdown extends line surge limit; (7)Accurate programmable current limit; (8)Optimized line feed-forward for line ripple rejection; (9)132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size; (10)Frequency jittering reduces EMI fi lter cost.
