LM2596 DC-DC Buck Converter Adjustable Step Down Power Supply Module

LM2596 DC-DC Buck Module

The LM2596 DC-DC Buck Converter Step-Down Power Supply Module is a step-down(buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version. The LM2596 series operates at a switching frequency of 150kHz, thus allowing smaller-sized filter components than what would be required with lower-frequency switching regulators.

This buck converter is internally compensated to minimize the number of external components to simplify the power supply design.

Since the LM2596 converter is a switch-mode power supply, its efficiency is significantly higher than popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller-sized filter components than what would be needed with lower-frequency switching regulators.

Features:

• Switching Frequency: 150KHz
• Rectification: Non-synchronous rectification
• Internally Compensated for minimized external components
• Efficient operation with higher input voltages compared to three-terminal linear regulators
• Short circuit protection for current limiting and recovery.

Pinout:

Applications:

• Used for USB on the go.
• Used for Point of load converters for PCs and laptops.
• Used for Battery Chargers.
• Used for Quad Copters.
• Used for Power audio amplifiers.
