LM2655MTC-3.

The LM2655MTC-3.3 is a switching regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

Specifications:

  • Output Voltage: 3.3V (fixed)
  • Input Voltage Range: 4V to 14V
  • Output Current: Up to 3A
  • Switching Frequency: 300kHz (adjustable)
  • Efficiency: Up to 95%
  • Operating Temperature Range: -40°C to +125°C
  • Package: TSSOP-16

Descriptions:

  • The LM2655MTC-3.3 is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated 3.3V output.
  • It integrates a high-side P-channel MOSFET and a low-side N-channel MOSFET for synchronous rectification.
  • The device includes features like soft-start, undervoltage lockout (UVLO), and thermal shutdown for protection.

Features:

  • Synchronous Buck Regulator: Improves efficiency by reducing power loss.
  • Adjustable Switching Frequency: Allows optimization for efficiency or component size.
  • Low Dropout Operation: Maintains regulation even when the input voltage is close to the output.
  • Soft-Start: Prevents inrush current at startup.
  • Undervoltage Lockout (UVLO): Ensures proper operation under low input voltage conditions.
  • Thermal Shutdown: Protects the device from overheating.

This information is based solely on the manufacturer's datasheet.
