Manufacturer: Texas Instruments

Part Number: AZ3842P

Description:

The AZ3842P is a high-performance current-mode PWM controller IC designed for offline and DC-to-DC converter applications. It provides precise control for switching power supplies with features like adjustable switching frequency, cycle-by-cycle current limiting, and under-voltage lockout (UVLO).

Key Features:

  • Current-Mode Control: Improves loop response and simplifies compensation.
  • Adjustable Oscillator Frequency: Up to 500 kHz.
  • Under-Voltage Lockout (UVLO): Ensures proper startup and shutdown.
  • Cycle-by-Cycle Current Limiting: Enhances protection against overloads.
  • High-Current Totem Pole Output: Directly drives power MOSFETs (up to 1A peak).
  • Low Startup Current: Typically 0.5 mA.
  • Wide Operating Voltage Range: 8.4V to 30V.
  • Precision Reference Voltage: 5V ±1%.
  • Package Type: 8-Pin DIP (Dual In-line Package).

Applications:

  • Offline power supplies
  • DC-DC converters
  • Battery chargers
  • Flyback and forward converters

This IC is commonly used in power management circuits requiring efficient and reliable switching control.
