NCP3065 LED Driver Acting Very Strange. Will not work with filter caps.

I have setup an LED regulator (NCP3065 - https://www.onsemi.com/pub_link/Collateral/NCP3065.PDF ) using On Semiconductors design tool and it seems to have some serious issues, if anyone could take a look and give some feedback?

Schematic: https://i.imgur.com/70YVN.png (Current circuit will not work with R3, C1, or C2) Works "flawlessly" without them.

The design is on a breadboard, but should be fine since the frequency is only in the kHz range.

C3 consists of ceramic capacitors (C0G I believe) for a total of 7nF

L1 is a 120uH inductor as it is the closest I had.

D2 is MB2060CT (https://www.fairchildsemi.com/ds/MB/MBR2060CT.pdf)

Ipk is .333Ohms

LED Sense is set at 0.5 Ohms


Input: 11v @ 110mA (Using a BK Precision 9110 Power Supply)

Output: 0.151v @ 265mA (Output into 3 Silicon Diodes for a load)

Scope Output using low inductance ground directly across the power supply rails: https://i.imgur.com/H3Hag.jpg (5v/div, 5uS/div)

As soon as I put a capacitor across the rails the oscillations die down and the chip heats up incredibly fast while dropping the output down to ~70mA (exact same as input current)

I've used this device in the past, and it worked well, using just the calculated values from the spreadsheet
(buck topology). I picked a value higher for the inductor, to ensure it would work due to tolerances.
Your inductor value looks low - is that what the spreadsheet calculated for you?
For my particular application at the time, the inductor value was higher (and I was operating at 150kHz).
I don't know if breadboard is good or not - the design was PCB based.
