They look very different [Led-driver-error] On the one I ordered the PWM input is clearly marked. On the other one I cannot see a PWM input, unless G is the common ground and CE is the PWM input. Does anyone know anything about the circuit they sent me in error?

Just a different layout and chip package. CE seems to be the PWM input. See the PT4115 datasheet . If you connect 12volt or so to Vin/GND then you should measure about 5volt on the unconnected PWM pin. [61t-Fh2yqUL.SL1024] Ignore the input voltage range on that image. Chips like that have usual…
