Descriptions:

The KA7525B is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications. It provides voltage-mode control with adjustable oscillator frequency, soft-start capability, and under-voltage lockout (UVLO) protection.

Features:

  • Voltage Mode PWM Control
  • Adjustable Dead-Time Control
  • Soft-Start Function
  • Under-Voltage Lockout (UVLO)
  • Precision 5.1V Reference Voltage
  • High-Current Totem-Pole Outputs
  • Synchronizable Oscillator
  • Error Amplifier with High Gain Bandwidth

This information is based on the original Fairchild Semiconductor datasheet for the KA7525B. For exact performance characteristics, refer to the official documentation.
