KA3525 PWM Controller IC – SMPS Control IC DIP-16

Description

KA3525 PWM Controller IC – SMPS Control IC DIP-16

The KA3525 PWM Controller IC is a versatile and widely used pulse-width modulation controller designed for regulating and controlling switched-mode power supplies. It integrates an internal oscillator, error amplifier, dead-time control, soft-start circuitry, and dual totem-pole outputs for driving external power transistors. Supplied in a DIP-16 through-hole package, the KA3525 is easy to use in both prototyping and production environments. This IC is commonly used in SMPS, DC-DC converters, inverters, UPS systems, and battery charging circuits, offering stable performance, precise duty-cycle control, and reliable operation in industrial and power electronics applications.

Applications

• Switched Mode Power Supplies (SMPS)
• DC-DC converters
• Inverters and UPS systems
• Battery chargers
• Power control and regulation circuits
• Industrial and automation electronics

How to Use

1. Set oscillator frequency using external resistor and capacitor.
2. Configure dead-time and soft-start as required.
3. Connect output pins to external MOSFET or transistor drivers.
4. Use proper feedback network for voltage regulation.
5. Ensure correct supply voltage and grounding for stable operation.
