How the circuit works? It is DC driver circuit of LED light?

 

Its a pwm chip...
Can you rotate your image 90deg clockwise..

Thanks.
I_Sense is applied to inverting terminal of OPAMP LM324 and then it is applied to pin no. 3 current sense of UC 2843. Is I_Sense input is integrated by opamp LM324 and then applied to UC2843?

 

Please find attached the rotated image.

Do you really think it is necessary to get that complicated to power an LED? What kind of LED is this?

 

Some LEDs come in 96V 100W ratings

This driver could work here.
LPF DC amp to 500kHz current mode PWM to boost regulator out

 

Thanks for the reply.
The driver is used to give output max 18W. 1W LEDs are used. For 18W 18 LEDs, for 15 W 15 LEDs ...
