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 Stepdown module is operating at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators Specification of HW-411A LM2596 DC To Dc Buck Converter Step Down Module: Model name: DC-DC LM2596S buck module Input voltage:3.2V~46V (recommended for use in 40V) Output voltage:1.25V~35V Output current:3A (maximum) Conversion efficiency:92% (highest) Output ripple:<30mV Switching frequency:65KHz Working temperature:-45 ~ 85 Dimension:21mm * 43mm * 14mm (length * width * height) Package Include: 1 x HW-411A LM2596 DC To Dc Buck Converter Step Down Module In Pakistan
