The step-down DC-DC Converter project presented here provides 3.3V @ 1A output from an input range of 8V to 36V DC. The adjustable current limit is an important feature of the project, which prevents the device from accidental output short circuits avoiding excessive load damage. The internal limiting current (latched function) has a typical value […]

https://www.electronics-lab.com/project/led-dimmer-for-super-high-brightness-leds/

This is a high-efficiency and reliability DC/DC converter with a dimming feature for super high brightness LEDs.  The project is built using L6902D chip. L6902 is a complete and simple step-down switching regulator with adjustable current limit. The current control loop with external sense resistors R6, R7, and R8 are able to work in constant […]
