PRECIsion Power SUpply project

PreciPSU, a high performance power supply project from Mare & Gal Electronics: PreciPSU is an attempt to build high performance power supply. The idea started few years ago but it was never realised. Some major target performance specs are as follows: three isolated channels around 50W per channel 24V/3A output per channel lowest possible ripple at fastest […]

Eagle Parts: TPS6120x DC/DC converter and KSZ8851SN Ethernet controller in a QFN packages

Today we added two relatively hard-to-solder parts to our library. Both come in QFN lead-less packages. First is the Texas Instrument’s TPS6120x DC/DC converter (pictured above)  with an integrated switch. The second is the Micrel KSZ8851SN embedded Ethernet controller (pictured below).

App note: Understanding switch-mode boost power stages

Boosting DC voltage is required in many applications, like LCD backlight, powering a 5v device with a battery and many more. This app note from Texas Instruments gives a detailed explanation on how it works and how to calculate all your components based on input/output specifications. The report includes detailed steady-stage and small-signal analysis of the boost power […]
