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.
