regulators that enable end product equipment to be compliant with low
standby power requirements. This device series combines the required
converter functions allowing a simple and economical power system
solution for office automation, consumer, and industrial products.
These devices are designed to operate directly from a rectified AC line
source. In flyback converter applications they are capable of providing
an output power that ranges from 6.0 W to 40 W with a fixed AC input
of 100 V, 115 V, or 230 V, and 3.0 W to 20 W with a variable AC input
that ranges from 85 V to 265 V.
eliminates the need for an auxiliary bias winding on the converter
transformer, fault detector and a programmable timer for converter
overload protection, unique gated oscillator configuration for extremely
fast loop response with double pulse suppression, power switch current
limiting, input undervoltage lockout with hysteresis, thermal shutdown,
and auto restart fault detection. These devices are available in
economical 8−pin dual−in−line and 4−pin SOT−223 packages.
