Specifications, Features, Applications

Enhanced EcoSmart , Integrated Off-Line Switcher with Advanced Feature Set and Extended Power Range

Lower System Cost, Higher Design Flexibility 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 heatsink required 35 W using P, G and M packages with universal input voltage and 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 Output Power Table

Heatsink is connected to SOURCE for low EMI Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset Fully integrated soft-start for minimum start-up stress Extended creepage between DRAIN and all other pins improves field reliability

Output Power Table. (for notes see page 2).

EcoSmart Energy Efficient Energy efficient over entire load range No-load consumption Less than at 230 VAC Standby power for 1 W input >600 mW output at 110 VAC input >500 mW output at 265 VAC input

Y Package Option for TOP259-261 In order to improve noise-immunity on large TOPSwitch-HX Y package parts, the F pin has been removed (TOP259-261YN are fixed at 66 kHz switching frequency) and replaced with a SIGNAL GROUND (G) pin. This pin acts as a low noise path for the C pin capacitor and the X pin resistor. It is only required for the TOP259-261YN package parts.

Description

TOPSwitch-HX cost effectively incorporates 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. Notes for Table 1: 1. Minimum continuous power in a typical non-ventilated enclosed adapter measured +50 C ambient. Use of an external heat sink will increase power capability. 2. Minimum continuous power in an open frame design +50 C ambient. 3. Peak power capability in any design +50 C ambient. 4. 230 VAC or 110/115 VAC with doubler. 5. Packages: L: eSIP-7F. See part ordering information. 6. TOP261 and TOP262 have the same current limit set point. In some applications TOP262 may run cooler than TOP261 due to a lower RDS(ON) for the larger device. 7. TOP256E package parts are available with Green (Halogen Free) mold compound. See Part Ordering Information on page 47. Parametrically green material encapsulated E package parts are identical to non-green parts.
