TECHNICAL DATA
IC for AC/DC Converter with built–in Power DMOS
Transistor with Operating Frequency 132 ± 8 kHz
Functional equivalent of TNY266 (Power Integrations)
IK3466
Description
IK3466 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.
