Quote:You are correct. My apologies. My search on Monoprice was for "HDMI to Composite" but their search engine came up with the reversed "Composite to HDMI", and I failed to notice the switch. However, both Amazon and eBay offer similar systems.
Quote:Basically, most linear power supplies utilize a transformer to step-down source voltage (ie: 110vac) to 5vac, 9vac, or 12vac, which is then rectified in an electronic circuit to convert it to dc voltage. Where there is a high current demand, a larger and heavier transformer is required. On average, a 9vdc-12vdc linear power supply will weigh-in at around one pound for each ampere of output. Thus, with higher amperage requirements linear power supplies become heavier, more expensive and less efficient. (Linear power supplies are only about 50% efficient.)
By the way, what's the difference between "switching" and "linear" power supplies?
Switching power supplies basically use electronic devices and circuits to regulate voltage and current output. They are more efficient (85%- 90%), weigh less, generally smaller in size and less expensive. However, one disadvantage of the basic switching power supply design is, it's electrically noisy and may require additional filtering circuitry.
Below is a picture of a switching power supply utilized with a Monoprice HDMI converter. (Note it's specs.)
A linear power supply with the same specifications would likely weigh-in around 3 pounds and cost much more.)
Quote:If you are referring to your power supply, I would recommend you try to find a replacement of the same type (Switching or Linear) and having exactly the same electrical input/output specifications.
Will these other converters you mention do ALL the same jobs the other one did? (I think you know what I mean.)
