Power Integrations TOP255/6/7/8/9/LN range of AC-DC converters

Power Integrations has added five devices to its TOPSwitch-HX range of AC-DC converters in 2mm-high e-SIP-L packages.

In comparison,  traditional TO-220 power packages previously used for power devices stand 18mm above the PCB and constrain the heatsink to a vertical aspect that often considerably exceeds this height.

This proprietary eSIP package features an ”L” shaped lead-bend enabling the devices to lie flat against the board with the exposed heatsink pad facing upwards, leaving space for a heatsink.

The package is designed to meet international standards for creepage and clearance, increasing reliability and improving resistance to contaminant-induced short-circuit failures, said the supplier.

The new products are the TOP255LN, TOP256LN, TOP257LN, TOP258LN and TOP259LN.
