In this video we will explore the design and working of a closed-loop 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 Op-Amp 04:54 - Differential Op-Amp 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.😅 #CircuitAnimation #DC_DC_Conversion
