ON Semiconductor

design the simple, non isolated AC/DC converter for

powering low voltage control part of mains applications

with triac, or SCR power switch. Some examples are:

dishwashers, microwave ovens, coffee machines, night

illumination and so on. In comparison with resistive, or

capacitive dropper is this solution more comfortable and

features some advantages such as:

greatly simplifies the total design and reduces time to

production. The new line of the Power Switchers, NCP1010

through NCP1014, is ideal for this purpose. This IC in the

SOT−223 package reduces size and is suitable for mass

production. The design consists of input filter, rectifier with

filtering capacitor, power stage with switcher and inductor,

output ultrafast rectifier, output filtering capacitor, feedback

loop with zener diode and optocoupler and indicating LED.

The only component necessary for proper powering of the

IC is the V

HV Drain circuit via internal voltage regulator. To eliminate

the noise at the feedback input, some small ceramic

capacitor with value of around 1.0 nF is necessary to be

connected as close to the FB pin, as possible.

The monolithic power switcher, used in this application,
