DC-DC Buck Converter Step Down Module LM2596 Power Supply Output 1.25V-35V

66

  • LM2596 Step Down Power Module design based on XL2596 as main control chip
  • Attached digital tube to display voltage at that time to highlight smart function
  • Schottky diode provides protection of reverse connection
  • The range of input voltage is 4.2~40V and output voltage is1.25V~37V ,which are continuously adjustable.(The input voltage must 1V higher than output voltage)

Features

1. With voltage meter display; voltage meter error of ±0.1V;the range among 0~40V. (note: to ensure the voltage meter accuracy, please make sure that the input voltage is 4.2V or more).
2.Voltage meter can be closed by long pressing button(minimum power loss).
3.The range of input voltage is 4.2~40V and output voltage is1.25V~37V ,which are continuously adjustable.(The input voltage must 1V higher than output voltage)
4.Maximum output current can be as high as 3A,but normal and stable working current is2A.
5.Use 150KHZ internal oscillation frequency, which is belong to the second generation of switch voltage regulator with low consumption and high efficiency.

Specifications:
  • Module Properties: non-isolated constant voltage module
  • Rectification: non-synchronous rectification
  • Input voltage: 4.5V-35V
  • Output Voltage(Less than input): 1.3V-30V
  • Output current: 3A maximum
  • Conversion efficiency: 92% (maximum)
  • Switching frequency: 150KHz
  • Output ripple: 50mV (maximum) 20M-bandwidth
  • Load regulation: ± 0.5%
  • Voltage regulation: ± 2.5%
  • Operating temperature: -40 ℃ to 85 ℃
Size: 48 * 23 * 14 mm ( 1 7/8 x 29/32 x 9/16 in )
