Yes PMP9762 is exactly what I needed. I had thought of a solution like that, but I was just afraid that applying a PWM signal on the EN pin could ruin the device in the long run.
In any case, I activate myself to order the reference design, and I do…
Hi Karne,
The TPS62135/6 differ only in their switching frequency. TPS62136 is slower, which makes it a little bit more efficient.
If you want lowest ripple, you should tie the MODE pin to Vin to get forced PWM mode. Efficiency at lower load currents…
Hi Oleksandr,
Thank you for your detailed explanation.
There is no internal pull-up structure on the TPS82130's EN pin. So, this voltage must come from outside the device. Did you monitor the EN pin with a scope to see the voltage rise to Vin? I…
Hi Lloyd,
Yes, most LED drivers are boost based and you need a buck. Would this type of solution work for you, if it supported 6A and a lower Vin? https://www.ti.com/tool/PMP9762
If so, then you need a lower Vin device with an SS/TR pin. 2 good ones…
