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.
