Working of UC 1845 PWM Boost Regulator in proteus simulation

The UC1845 is a pulse-width modulation (PWM) controller IC (integrated circuit) commonly used in boost converter circuits to regulate and control the output voltage. It is part of the UCx84x family of devices manufactured by Texas Instruments, which are widely used in power supply and voltage regulation applications. The UC1845, in particular, is known for its versatility and is used in various power supply topologies, including boost converters.
