KL-224/50,8/SW/V/I is a three-terminal integrated circuit (IC) thermally insulated with a heatsink from Seifert. It is designed for use in switched mode power supplies (SMPS) and power factor correction circuits. It features a synchronous rectified buck-boost controller, and provides a better balance between power consumption and power supply load requirements. It is available in several heatsink configurations, including extruded U-shaped, SOT32, SOT93, TO126, TO218, TO220, TO247, TOP3. Additionally, KL-224/50,8/SW/V/I has built-in over-current, overload protection, as well as short-circuit and temperature protection.
