In the first circuit a flasher circuit in series with a 220 ohm resistor turns on a power transistor. In the second circuit, a power FET is used in place of the NPN. A pull-down resistor is added to pull the gate low when the circuit turns off. Don't hesitate to modify this basic circuit to meet your specific requirements.
While either of the capacitors is charged, the base voltage of the transistor is negative, thus the transistor remains OFF. The frequency of this is related to the time needed for the capacitor to discharge (when it is connected in reverse polarity to ground via a resistor - e.g. C1-R2). LED Flasher circuits usually work on the same principle.
This IC creates pulses of current at a specific time interval, and we will use these pulses to turn the LED on and off, hence it will work as an LED flasher circuit. The time interval of the pulses can be controlled by changing the value of resistors and capacitors used in the circuit.
