Manufacturer: Texas Instruments

Part Number: AZ3844P

Description:

The AZ3844P is a current-mode PWM controller IC designed for switching power supply applications. It provides the necessary features to implement fixed-frequency current-mode control schemes with minimal external components.

Key Features:

  • Current-Mode Control: Improves loop response and simplifies compensation.
  • Adjustable Switching Frequency: Up to 500 kHz.
  • Under-Voltage Lockout (UVLO): Ensures proper operation under low input voltage conditions.
  • High-Current Totem Pole Output: Directly drives power MOSFETs.
  • Precision Reference Voltage: 5V ±1% accuracy.
  • Low Start-Up Current: Typically 0.5 mA.
  • Cycle-by-Cycle Current Limiting: Enhances system protection.
  • Operating Temperature Range: -40°C to +85°C.
  • Package: 8-Pin DIP (Dual In-Line Package).

Applications:

  • Offline and DC-DC converters
  • Flyback and forward converters
  • Power supply modules

Note: This part may be obsolete or have alternative replacements. Verify availability with the manufacturer or authorized distributors.
