I'm having a hard time finding a buck-boost controller that fits my needs. I need an output up to 50W with a wide input/output voltage range. What I'd like is either voltage mode control or current mode control with inductor DCR current sensing. I also want a 4 switch controller (synchronous) and that's what really narrows the field.
Oh, I saw in another thread TI will be releasing the LM5175 this year which sounds like what I'm looking for. I'm not in any rush for this design so maybe I'll just wait it out. Would love to see some cursory specs on it.
