TPS62913: Higher current solution

fls20

Part Number: TPS62913
Other Parts Discussed in Thread: TPS62180

Do you have a higher current (6A or 8A) version of TPS62913 ready or planned?

Is it possible to add a ferrite bead filter stage into control loop to some existing 6A-8A DC/DC converter (D-CAP3, TPS68215, or dual-phase, TPS62180 like solution) to achieve comparable low noise performance?

Thanks!

Hello,

Thank you for your inquiry. Can you provide details on your application that needs higher current for a low noise, low ripple solution?

To achieve low noise performance (~100Hz to 100kHz), the switching converter needs to be specifically designed to achieve that.

To achieve low ripple (at the switching frequency and above), it is possible to use a variety of techniques to reduce the output ripple. We have a presentation avaialble that goes through the different techniques such as ferrite bead filter, larger inductance, multiple output caps, three-terminal filter cap, and more here: https://www.ti.com/lit/ml/slup404/slup404.pdf

Hello,

we're looking for 1V 6A-8A LDO-like source for high speed SERDES analog power planes of a digital switching ASIC. This kind of load doesn't require ultra-low noise, and no special load step performance is needed.
