Salutations. Welcome back to my Channel. In today's video I'll share with you a rather handy project involving a Switching Power Supply (DC DC Boost Converter) built around the UC3843 Current Mode PWM IC. The circuit can be used as a Battery charger, Flood light LED Driver, or general purpose variable Bench Power Supply for voltages between 12-60V DC, and 100Watts of power for extended periods of time. Ensure to use quality components and don't forget to mount the Power MOSFET and diode on ample sized heat sinks.
Thanks for watching, and I hope you enjoyed and learned something new. Don't forget to LIKE, SHARE, and SUBSCRIBE for more!
