Inverted buck-boost of LED driver

Question

I would like to use an LED whose Vf is around the input voltage. Since there is a concern that unstable operation may occur when switching between booster operation and step-down operation with a simple buck-boost IC, we are focusing on the inverting buck-boost operation of the LT3744, which seems to be able to operate the LED stably. However, as a lineup, I could only find the LT3744, which is likely to be able to perform inverting buck-boost operation. Is there any other lineup for inverting buck-boost operation?

Hi K.T, 
 I think only LT3744 has that unique inverting buck-boost operation. However, buck-boost converters from ADI are assured to be working in stable operation. I suggest reviewing and/or trying LT8391 or LT8391A. 
 If issues persist, I suggest contacting local FAE or I can help connect you to one if you can provide project info and estimated annual usage. Alternatively, you can submit a support ticket through this link: Technical Support Form | Analog Devices
