Anyone know whether this is a thinly disguised MC34063?

Its definitely a switcher of some sort.

Thanks.

It's a clone of MC34063 Switching Regulator.
I've seen it on websites that they're offered as a direct replacement
for MC34063.

Thanks - it sort of crossed my mind that the CHN prefix might stand for the
Chinese cheapie version.

As it happens I bought a quantity of 34063 from Farnell a while back - a
couple of cheap clones might do for times I determine component values
empirically.
