KA7500C is a pulse width modulation (PWM) control IC manufactured by SAMSUNG.

The KA7500C is a pulse width modulation (PWM) control IC manufactured by SAMSUNG. Below are its specifications, descriptions, and features based on factual information:

Specifications:

  • Type: PWM Controller IC
  • Manufacturer: SAMSUNG
  • Package: DIP-16 (Dual In-line Package)
  • Operating Voltage: 7V to 40V
  • Output Current: Up to 200mA (sink/source)
  • Oscillator Frequency Range: Adjustable (typically 1kHz to 300kHz)
  • Duty Cycle Range: Adjustable (0% to 100%)
  • Internal Reference Voltage: 5V (±1%)
  • Operating Temperature Range: -20°C to +85°C

Descriptions:

  • The KA7500C is a fixed-frequency PWM controller designed for power supply regulation.
  • It is functionally equivalent to the TL494 and can be used in push-pull or single-ended configurations.
  • It includes an onboard oscillator, error amplifiers, a dead-time control comparator, and an output control circuit.

Features:

  • Adjustable dead-time control for push-pull or single-ended operation.
  • Onboard 5V reference voltage with high accuracy (±1%).
  • Dual error amplifiers for feedback control.
  • Uncommitted output transistors (NPN) for flexible output configurations.
  • Under-voltage lockout (UVLO) protection.
  • Compatible with the TL494 and other industry-standard PWM controllers.

This information is based on the manufacturer's datasheet and technical documentation.
