Product Summary

The TOP256YN is an enhanced ecosmart, integrated off-line switcher. The TOP256YN 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: 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)Low thermal impedance junction-to-case (2 ℃ per watt); (4)Low height is ideal for adapters where space is limited; (5)Simple mounting using a clip to aid low cost manufacturing; (6)Horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications; (7)Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink; (8)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; (9)Output overvoltage protection (OVP) is user programmable for; (10)latching/non-latching shutdown with fast AC reset; (11)Allows both primary and secondary sensing; (12)Line undervoltage (UV) detection prevents turn-off glitches; (13)Line overvoltage (OV) shutdown extends line surge limit; (14)Accurate programmable current limit; (15)Optimized line feed-forward for line ripple .
