00:00Best Power Switch I Sees Under $5.50 Video Script
00:05Paragraph 1. Hook
00:07Ever had a USB port, or a board rail, that keeps tripping itself the second you plug something in?
00:13That's exactly what a current limited power switch I see is built to prevent.
00:17I went through thousands of sold listings to find the best power switch I see under $5.50,
00:22and one of these five is shockingly cheap.
00:25Five parts, five jobs, let's walk them.
00:28Paragraph 2. TPS 2041 BD-BVR, 10-Piece Asodi 23-5
00:34First up, the TPS 2041 BD-BVR, 10-Pieces for $7.34.
00:40This is the tiny Asodi 23-5 package, five pins, and it's the smallest footprint in this whole lineup,
00:47so it disappears on a crowded board or a solderable breadboard pad.
00:51Rated around 4.5 stars across nearly 5,000 sales.
00:55The chip is marked PLIA, so you know exactly what you're grabbing when the bag arrives.
01:00If you're tight on space, this is the one.
01:04Paragraph 3. TPS 2553 DRR, 10-Piece Asodi, WSON 6
01:10This is probably the steal of the bunch.
01:13The TPS 2553 and WSON 6, 10-Pieces for $3.51, that's about $0.35 a chip.
01:20It's a USB current limited switch, and the big deal is the adjustable current limit,
01:25you set it with a resistor instead of living with a fixed number.
01:294.9 stars, 4,700 sold.
01:33For anything USB-powered, this is the easy buy.
01:37Paragraph 4, TPS 2013 DR, 10-Piece As, 8-SoIC
01:42The TPS 2013 is the muscle car of the group, 2.6 amps of current limited power distribution in a
01:48standard 8-pin SOIC.
01:5010-Piece is for $9.80, so roughly a dollar a piece, and it's rated $4.9 as well.
01:55If your load is heavier, like a motor, a heater, or a sensor array, this is the part that won't
02:01flinch.
02:02An 8-pin SOIC means it fits a breadboard with zero fuss.
02:06Paragraph 5, TPS 2041 DR, 5-Piece As, 8-SoIC
02:11Now the bigger package version of the 2041, the listing calls it a 900mA current limited power distribution switch, 5
02:19pieces for $17.93.
02:21That works out to about $359 a chip, which is the highest per-piece price here, though still comfortably under
02:27$5.50 each.
02:284.8 stars.
02:30You pay more per chip for the easier footprint and easier probing.
02:35Note, not part of script only product 2, $3.51, clears $5.50 on lot price.
02:42The other 4 clear it per chip, $0.73, $0.98, $3.59, $1.85.
02:50Script says under $5.50 per unit to stay accurate, flip the framing to lot price if the listing set
02:56changes.
02:57Also worth an on-screen caveat, these are third-party market parts, check TI's genuine marking and buy with returns
03:03before taping out a board.
03:04Blank It per album for seed, slide $4.50 per unit to go as good as $5.50 per unit.
03:05Terima kasih.
