High Efficiency PWM LED Dimmer Control Circuit

Led dimmer PWM circuit with LM358 opamp technique used can be used as LED flashlight. All information about the project ( provided.

This webpage describes a highly efficient LED dimmer, or a dimmable LED flashlight, or a switching current source, or whatever you want to call it. Cheap, single-IC, uses commonly available parts, easy to build. Designed to get the longest light out of a (rechargable) battery, ideal in emergency situations: some 24+ hours for a single white LED at full brightness from a cheap 9V, 200mAh battery. Works well from 4 up to at least 30 Volts; may even vary over time, while the brightness level is maintained essentially constant. Can drive as many LEDs
