KA7500C INTEGRATED CIRCUIT DIP-16

The KA7500C INTEGRATED CIRCUIT DIP-16 is a versatile pulse-width modulation (PWM) controller designed for switching power supplies. Encased in a standard 16-pin DIP (Dual In-line Package), this IC offers a comprehensive set of features for controlling and regulating power conversion processes. It is widely used in various power supply applications, including AC-DC adapters, DC-DC converters, and uninterruptible power supplies (UPS). The KA7500C provides precise control over the output voltage and current, ensuring stable and efficient power delivery. Its built-in protection features safeguard the power supply against overvoltage, overcurrent, and short-circuit conditions.

The KA7500C features a wide operating voltage range, typically from 4.5V to 30V, providing flexibility in circuit design. Its internal oscillator can be programmed with external components to set the desired switching frequency. The IC includes a voltage reference, error amplifier, PWM comparator, and output drivers, providing all the necessary functions for a complete PWM control system. The DIP-16 package is easy to handle and solder, making it suitable for both prototyping and mass production. The KA7500C's high efficiency and low standby current contribute to energy-efficient power supply designs.

Key specifications of the KA7500C include a maximum operating frequency of 500 kHz, a voltage reference accuracy of ±1%, and an output current capability of 200 mA. Its dead-time control feature allows for adjusting the minimum on-time of the output pulses, preventing shoot-through currents and improving efficiency. The IC's soft-start function gradually increases the output voltage during startup, reducing stress on the power supply components. The KA7500C's overvoltage protection circuit shuts down the output when the output voltage exceeds a predetermined threshold, preventing damage to the load.
