Shunt regulator demo

Designing microcontroller-based battery charge regulators for the SLA battery pack in my electric car- see my other videos. For more information, check acuteaero.com . Had considered simply making zener regs, but there was a lead time on the batteries, so I decided to do it right.

with Kelly Consoer video.linear.com Modern FPGAs and servers operating at low voltages are sensitive to subtle supply drops. The droop may result from a combination of excess regulator noise, insufficient bandwidth in the supply regulator, excess ESR & ESL in the decoupling components, or distributed inductance in the power distribution. To abate the risk of supply droop the typical approach is to surround the processor with an assortment of ceramic and bulk capacitors, thereby lending broadband support to the supplies with capacitors. This consumes board area and component budget. Linear Technology's LT3070 is a POL regulator designed for FPGA & server applications. The LT3070 commands high bandwidth and fast transient performance by providing lower output impedance than bulk capacitors, thus eliminating the need for bulk capacitors. With the LT3070, the distributed decoupling network is reduced to just a few small ceramic capacitors. The high bandwidth combined with a 25uVRMS noise floor, make the LT3070 the fastest, quietest, lowest dropout, and most cost effective 5A monolithic linear regulator in the industry.

If you want to give your 8800GT the "silent treatment" a good option is the $30 Accelero S1 Rev.2 - When I researched this cooling option one of the few recurring complaints were about the lack of a provided heat sinks for the voltage regulators. This mod shows how to use the provided sinks to work for the 8800's regulators.
