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.
