Power Integrations’ TOPSwitch-HX family of AC/DC power conversion ICs are appropriate for adapters for notebook computers, LCD monitors and flat-panel TVs from 20 to 100 W. The eSIP-L-packaged devices combine a 700 V switching power MOSFET with controller and supervisory functions into a single monolithic IC while utilizing a TOP261 chip. The ENERGY-STAR® 2.0-specified ICs enable the PCB, chip and heatsink to lie parallel to each other using a 90° pin deflection. The components stand 2 mm above the board and come in models including the TOP260LN, TOP261LN and TOP262LN.
