Description

The TOP258GN-TL 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.To optimize power supply effi ciency, four different control modes are implemented.  At maximum load, the modulator operates in full frequency PWM mode; as load decreases, the modulator automatically transitions, fi rst to variable frequency PWM mode, then to low frequency PWM mode.

Features of the TOP258GN-TL are:(1)low height is ideal for adapters where space is limited; (2)simple mounting using a clip to aid low cost manufacturing; (3)horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications; (4)extended package creepage distance from DRAIN pin to adjacent pin and to heat sink; (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.

The absolute maximum ratings of the TOP258GN-TL can be summarized as:(1)lead temperature:260;(2)storage temperature:-65 to 150;(3)operating junction temperature:-40 to 150;(4)drain peak voltage:-0.3 to 700V;(5)control current:100mA.The primary sensed OVP protection circuit shown in Figures 41, 42 and 43 is triggered by a signifi cant rise in output voltage (and therefore bias winding voltage).  If the power supply is operating under heavy load or low input line conditions when an open loop occurs, the output voltage may not rise signifi cantly.Under these conditions, a latching shutdown will not occur until load or line conditions change.  Nevertheless, the operation provides the desired protection by preventing signifi cant rise in the output voltage when the line or load conditions do change.Primary side OVP protection with the TOPSwitch-HX in a typical application will prevent a nominal 12 V output from rising above approximately 20 V under open loop conditions.
