KA3842 is a pulse-width modulation (PWM) controller IC manufactured by Samsung.

The KA3842 is a pulse-width modulation (PWM) controller IC manufactured by Samsung. Below are its specifications, descriptions, and features:

Specifications:

  • Manufacturer: Samsung
  • Type: Current Mode PWM Controller
  • Operating Voltage Range: 8V to 30V
  • Output Duty Cycle: 0% to 100%
  • Switching Frequency: Up to 500kHz
  • Output Current (Peak): ±1A
  • Reference Voltage: 5V (±1%)
  • Operating Temperature Range: -20°C to +85°C
  • Package Type: DIP-8, SOIC-8

Descriptions:

The KA3842 is a fixed-frequency current-mode PWM controller designed for offline and DC-to-DC converter applications. It provides precise control of switching power supplies with features like under-voltage lockout (UVLO), current sensing, and adjustable oscillator frequency.

Features:

  • Current-Mode Operation: Improves loop response and simplifies compensation.
  • Under-Voltage Lockout (UVLO): Ensures proper startup and shutdown.
  • Trimmed Oscillator: Provides accurate frequency control.
  • High-Current Totem Pole Output: Directly drives power MOSFETs.
  • Pulse-by-Pulse Current Limiting: Enhances system protection.
  • Low Startup and Operating Current: Improves efficiency.
  • Internal Reference Voltage: 5V with tight tolerance (±1%).

This IC is commonly used in switch-mode power supplies (SMPS), battery chargers, and DC-DC converters.
