IC for AC/DC Converter with built–in Power DMOS Transistor with Operating Frequency 132 ± 8 kHz Functional equivalent of TNY266 (Power Integrations) Description HT3466 is IC for AC/DC converter with build–in power switch with operating frequency 132 ± 8 kHz realized on the base of high-voltage BiCDMOS process. IC performs driving of power built in MOSFET switch, quantity of energy transferred to load is regulated by means of MOSFET on-time. So output voltage practically doesn’t depend from load. The IC is purposed for adapter battery chargers of the mobile phones, reserve power supply of PC, TV-sets, AC- adapters, electrical equipment control units, Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL) network termination.
