KA3525A Description

Short technical summary and product information.

The KA3525A is a monolithic integrated circuit used as a pulse width modulation (PWM) controller. It includes control circuitry such as a voltage reference, error amplifier, oscillator, soft start, and output driver, making it suitable for switch-mode power supplies and other electronic regulation circuits. The device operates with a supply voltage of around 40V and provides a reference output current of approximately 50mA. Its operating temperature range is from 0°C to 70°C, with storage capabilities from -65°C to 150°C. The package type is a 16-pin PDIP, designed for through-hole mounting. The IC generates two complementary PWM signals, with feedback circuitry controlling the output voltage. It features shutdown protection when feedback signals approach limits, and soft start functionality to prevent inrush current. The device's output sink current is 500mA, and power dissipation is 100mW, suitable for various power regulation applications.
