Questions about the Linear vs Switching poster

What’s on the Linear vs Switching poster?

Linear regulator against Switching regulator, side by side. Linear regulator: Passes current through a control device; Linear regulator: Efficiency roughly V_out ÷ V_in; Linear regulator: Very low output noise; Linear regulator: Steps voltage down only; Linear regulator: Needs heatsinking at real current; Switching regulator: Chops and filters at high frequency; Switching regulator: Efficiency often above 90%; Switching regulator: Ripple and EMI at the switching rate; Switching regulator: Steps up, down or inverts; Switching regulator: Needs an inductor and careful layout; Dropping 12 V to 5 V at 1 A wastes 7 W in a linear regulator and well under 1 W in a…. Low-noise analogue front ends often use both: a switcher for the bulk conversion, then a small linear regulator to clean it up.

Who is the Linear vs Switching poster for?

Linear vs Switching belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning electronics can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Linear vs Switching poster?

Choose by the voltage drop and the current: below a watt of waste, linear usually wins. A wall chart earns its place by being glanceable from where the work is happening, so Linear vs Switching belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Linear vs Switching?

BJT Operating Regions, BJT vs MOSFET and Common-Emitter Amp sit alongside Linear vs Switching in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.BJT Operating RegionsBJT vs MOSFETCommon-Emitter Amp

Is the Linear vs Switching poster free to download and print?

Yes. Linear vs Switching downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Linear vs Switching poster print at?

Linear vs Switching is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Linear vs Switching loses nothing.Printing guide
