OZ9925, a PWM controller for CFL lamps without data sheet

I found this pin assignment:

1	?
2	Power supply +12V
3	push-pull driver output #1
4	GND
5	push-pull driver output #2
6	GND
7	Sawtooth generator R and C
8	?
9	Dimmer control input, guessing more voltage = more bright
10	Voltage(?) feedback input
11	? (always LOW)
12	Switch-On input/output (for soft start?), shows an ongoing voltage ramp on power-on
13	seems to be a power-good output, H = lamps are bright
14	on/off control input, H = ON, L = OFF
15	?
