Description

LM2596 DC-DC Buck Converter Step Down Module Power Supply is a step-down(buck) switching regulator. LM2596 Buck  is 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.

Features of LM2596 DC-DC Buck Converter Step Down Module Power Supply:

  • Output ripple: 30mA9maximum
  • Load Regulation: ± 0.5%
  • Voltage Regulation: ± 0.5%
  • Dynamic Response speed: 5% 200uS
  • Input voltage:4.75-35V
  • Output voltage:1.25-26V(Adjustable)
  • Output current: Rated current is 2A, maximum 3A(Additional heat sink is required)
  • Conversion Efficiency: Up to 92% (output voltage higher, the higher the efficiency)
  • Rectifier: Non-Synchronous Rectification
  • Module Properties: Non-isolated step-down module (buck)
  • Short Circuit Protection: Current limiting, since the recovery
  • Operating Temperature: Industrial grade (-40 to +85 ) (output power 10W or less)
