LM2596 Buck Converter Step-Down Power Module

DC-DC Buck Converter Step Down Module LM2596 Power Supply 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 3.3 V, 5 V, 12 V, 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 device is internally compensated to minimize the number of external components to simplify the power supply design.

Features:

1. Module Properties: non-isolated constant voltage module
2. Rectification: non-synchronous rectification
3. Input voltage: 4.5V-35V
4. Output Voltage (Less than input): 1.3V-30V
5. Output current: 3A maximum
6. Conversion efficiency: 92% (maximum)
7. Switching frequency: 150KHz
8. Output ripple: 50mV (maximum) 20M-bandwidth
9. Load regulation: ± 0.5%
10. Voltage regulation: ± 2.5%
11. Operating temperature: -40 °C to +85 °C

Package Includes:

1 x LM2596 DC-DC step Down Module.
