บอร์ดปรับแรงดันไฟลง LM2596 DC-DC Adjustable Step Down Power Module 3.2-40V to 1.25V-30V 3A DC-DC (BUCK-LM2596)

apable of driving a 3-A load with excellent line and load regulation. Available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version. operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. 3.3-V, 5-V, 12-V, and Adjustable Output Versions Adjustable Version Output Voltage Range: 1.2-V to 37-V \u00b1 4% Maximum Over Line and Load Conditions Available in TO-220 and TO-263 Packages 3-A Output Load Current Input Voltage Range Up to 40 V Requires Only 4 External Components Excellent Line and Load Regulation Specifications 150-kHz Fixed-Frequency Internal Oscillator TTL Shutdown Capability Low Power Standby Mode, IQ, Typically 80 \u00b5A High Efficiency Uses Readily Available Standard Inductors Thermal Shutdown and Current-Limit Protection Simple high-efficiency step-down (buck) regulator On-card switching regulators Positive to negative converter 1 * LM2596 Step Down เพาเวอร์ซัพพลายโมดูลตัวแปลงแรงดันไฟ DC
