Monolithic High Voltage

Gated Oscillator Power

Switching Regulator

The NCP1050 through NCP1055 are monolithic high voltage

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.

This device series features an active startup regulator circuit that

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.
