In this video we will explore the design and working of a closedloop buck converter.
From its basic circuit to feedback driven circuit, we will explore it completely.

Correction: 6:05 The duty cycle of PWM "increases".

Chapters:
00:00 Introduction
00:17 PWM
01:12 Adding Inductor
02:30 Frequency Increase
02:45 Adding Capacitor
03:52 Basic Buck Converter
04:13 Closed Loop Buck Converter Circuit
04:20 Operational Amplifier or OpAmp
04:54 Differential OpAmp
05:30 PWM Generator
06:08 MOSFET
07:00 Supply and Reference Voltages
07:25 Normal Load (Output Voltage High)
07:37 Double Load (Output Voltage High)
08:05 Change Output Voltage
08:23 Important Points
08:28 1) Voltage Divider
09:00 1.5) Load Change
09:21 2) PWM Generator (Reversed Comparator Inputs)
09:40 Outro

The feedback does changes at 07:37 (Small change) but due to compression (Video + YouTube), The color doesn't change.
