The KA3525A is manufactured by Onsemi, which provides high-performance, energy-efficient solutions for a range of applications, including automotive, communications, computing, consumer electronics, industrial, LED lighting, medical, and power supplies. . Today I built a 50Hz oscillator circuit using the KA3525 IC to drive a high-frequency transformer and convert 12V DC into 220V AC. This circuit is the core of many DIY inverters, and in this video, I walk you through every step of the process — from theory to real testing. 🔧 What's inside this. . The KA3525A is a pulse width modulation (PWM) controller. It integrates all the necessary circuitry to control a switching power supply in a single package, including a voltage reference, error amplifier, oscillator, pulse width modulator, and output driver. Didn't Find any proper synchronous buck converter, As some boost converter or dc to ac inverter are common. Using KA3525 to generate 50 Hz, you drive the bridge at 50Hz and so the bridge outputs an AC voltage with 50Hz frequency. You also need to use a hi/lo side MOSFET driver for the H-bridge like IR2110/L6385.
