Product Highlights
Lower System Cost, Higher Design Flexibility
● Multi-mode operation maximizes eficiency at all loads
● New eSIP-7F and eSIP-7C packages
● Low thermal impedance junction-to-case (2℃ 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 up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC
● Output over voltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
● Allows both primary and secondary sensing
● Line under voltage (UV) detection prevents turn-off glitches
● Line over voltage (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 jttering reduces EMI filter cost
● 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
EcoSmart - Energy Efficient
● Energy efficient over entire load range
● No-load consumption
● Less than 200 mW at 230 VAC
● Standby power for 1 W input
● >600 mW output at 110 VAC input
● >500 mW output at 265 VAC input
Description
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.
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.

The goods are received on time, until I checked, as I will check the feedback. The seller sent on time, everything came safe and sound.
