KA7524 is a switching regulator controller IC manufactured by Samsung.

The KA7524 is a switching regulator controller IC manufactured by Samsung. Below are its specifications, descriptions, and features:

Specifications:

  • Manufacturer: Samsung
  • Type: Switching Regulator Controller
  • Package: DIP-16 (Dual In-line Package)
  • Input Voltage Range: 8V to 40V
  • Output Voltage: Adjustable
  • Switching Frequency: Fixed (typically 40kHz)
  • Output Current: Depends on external components
  • Duty Cycle: Adjustable
  • Operating Temperature Range: -20°C to +85°C

Descriptions:

The KA7524 is a PWM (Pulse Width Modulation) controller IC designed for DC-DC converter applications. It provides control for switching power supplies with adjustable output voltage and current limiting. The IC includes an internal oscillator, error amplifier, PWM comparator, and a high-current output driver for driving external power transistors.

Features:

  • Adjustable Output Voltage – Allows flexibility in power supply design.
  • Current Limiting Protection – Safeguards against overcurrent conditions.
  • Internal Reference Voltage – Ensures stable regulation.
  • Soft-Start Function – Reduces inrush current during startup.
  • Under-Voltage Lockout (UVLO) – Prevents operation below the minimum input voltage.
  • High-Current Totem Pole Output – Capable of driving power MOSFETs or bipolar transistors.
  • Low Standby Current – Improves efficiency in standby mode.

This IC is commonly used in power supply circuits, battery chargers, and DC-DC converters.

(Note: The KA7524 may be obsolete or replaced by newer alternatives. Always verify datasheet availability before design implementation.)
