  Part Number: LM5115 Dear E2E, I'm testing an LM5115 operating as an SSPR where the main converter is an active clamp forward. The VIN to the forward is 38V to 140V, and the forward xfmr has a 2:1 ratio. The output voltage of the forward converter is…

  Part Number: LM5115 Hi TI LM5115 does not have enable pin, if I want to turn off the output due to protection requirements. Whether VCC power can only be turned off, or there are other ways? Thanks. Jerry

  Part Number: LM5115 Dear E2E, I've built an SSPR with this controller, and it works well. But the control loop bandwidth is quite low, only around 1 kHz. The device itself has a novel mix of voltage mode, VIN feed-forward and current mode control. Do…

  Part Number: LM5115 Dear E2E, With the help of the small signal model from David Baba I was able to improve the bandwidth and the DC gain of my SSPR using the LM5115. Since the power stage response is mostly a steady -20 dB/dec slope from low frequency…
