IC for AC/DC Converter with built

–in Power DMOS

Transistor with Operating F

requency 132 ± 8 kHz

Functional equivalent of TNY266 (Power Integrations)

Description

IK3466 is IC for AC/DC converter with build

–in power

switch with op

erating 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.

Features



Programmable line under-voltage detect circuit

prevents power on/off glitches and minimizes

quantity of external components



132 kHz operation frequency



High output voltage stability



Simple ON/OFF control, no loop compensation

needed



No load consumption < 50 mW with bias winding

and < 250 mW without bias winding at 265 V (AC)

input



High input (supply) voltage makes IC ideal for

charger applications



High bandwidth provides fast turn on with no

overshoot



Built-in current limit and thermal protection circuits

provide high safety



Built-in automatic restart circuit provides short circuit

and open loop protection



Undervoltage detection function
