Re: SMPS - Can they all handle wide range of Input Voltage?
Test (experiment) Over !
NO BOOOM !
For good measure now being used in an Australian LG VCR/DVD player - all good so far all day nothing in there getting hot or bothered....its a happy ending!Last edited by ketone; 12-22-2022, 12:22 AM.Comment

Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

AD7276, AD7277, AD7278, AD7274, AD7273
The AD7276, AD7277, AD7278, AD7274, AD7273 are 12-bit/10-bit/8-bit, high speed, low power, successive approximation analog-to-digital converters (ADCs), respectively. The parts operate from a single 2.35V to 3.6V power supply and feature throughput rates of up to 3 MSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 55 MHz.
The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors...10-07-2024, 05:32 AM -
For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
What kind of PSU?
I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?
Currently have a 120/220V switchable SMPS I want to see if I... -
The TPS51427A TPS51427ARHBT TPS51427ARHBR are dual synchronous step-down controllers designed for laptop and mobile communications applications. This device is part of a low-cost suite of notebook power bus regulators that enables system designs with low external component counts.
The TPS51427A includes two pulse-width-modulation (PWM) controllers, SMPS1 and SMPS2. The output of SMPS1 can be adjusted from 0.7V to 5.9V, while the output of SMPS2 can be adjusted from 0.5V to 2.5V. This device also features a low-dropout (LDO) regulator that provides a 5-V/3.3-V output, or adjustable...10-23-2024, 02:37 AM -
This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.
Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...
