Descriptions:

The KA7500B is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications. It provides precise voltage regulation through pulse-width modulation control. The IC includes an internal oscillator, error amplifier, dead-time control comparator, and output drivers. It is widely used in switch-mode power supplies (SMPS), inverters, and motor control circuits.

Features:

• Complete PWM Control Circuitry
• On-Chip Error Amplifier
• Adjustable Dead-Time Control
• Internal Soft-Start Function
• Under-Voltage Lockout (UVLO) Protection
• Synchronous Operation Capability
• Compatible with TL494 and MB3759
