With an ultralow-profile package, the TOPSwitch-HX IC power-package family suits use in 65W adapters for notebook computers and 20 to 100W power supplies for LCD monitors and flat-panel TVs. The switcher ICs meet Energy Star 2.0 specifications for external adapters and target reference designs, such as the DER-196, for a 65W notebook adapter measuring slightly larger than a standard deck of playing cards. An L-shaped lead bend allows the vendor's eSIP package to lie flat against the PCB with the heat-sink pad facing up. Combining a 700V switching-power MOSFET with controller and supervisory functions, the 2-mm-high IC also provides space for a heat sink. Available in eSIP-L packages, the TIP260LN, the TOP261LN, and the TOP262LN IC power packages suit 20 to 100W power levels and cost $1 (10,000).
