12v 350 watt power supplies are very common when using various light controller boards (SanDevices, Falcon16, LOR CMB24D, etc.). This video does a quick walk... The schematic in Figure 1 depicts a notebook adapter power supply employing the Power Integrations® TOPSwitch®-HX TOP258EN off-line switcher in a fl yback configuration. This power supply operates from a universal input to provide a 19 V, 65 output capable of operation in a sealed enclosure at an ambient temperature of up to 40 °C.
Jul 17, 2012 · To accomplish this most all power supplies have separate voltage and current feedback control loops to limit either the output voltage or current, depending on the load. To illustrate this Figure 1 shows a circuit diagram of a basic 5 volt, 1 amp output series regulated power supply operating in CV mode.
Multi-Output Power Supply (Output 12V, 5V, 3.3V, 1.2V to 10V) The multi-output power supply is a very useful project for hobbyist, the small module provides 12V, 5V, 3.3V, and 1.2 V to 10V adjustable from 15V to 30V 3A DC input. If you have a spare laptop power adapter can help as an input power source. Can power many Arduino projects.
