From the shop's description

LM2596T-12 Buck Fixed 40V 12V 3A TO-220-5L DC-DC Converters DIP IC The LM2596T-12 Buck Fixed 40V 12V 3A DC-DC Converter DIP IC is a sophisticated, monolithic integrated circuit specifically designed for use as a step-down (buck) switching regulator. This component offers a high-efficiency solution for converting a higher input voltage to a stable, fixed 12V output voltage, all while delivering a substantial output load current of up to 3A. Its primary advantage lies in its simplicity of use, as it requires minimal external components—typically only an inductor, a few capacitors, and a diode—to form a complete, robust power supply circuit. This significantly simplifies design and reduces overall solution size and cost compared to non-integrated switching solutions. Features: Fixed output voltage of 12V, eliminating the need for external divider resistors. Wide input voltage range up to 40VDC. Guaranteed 3A output load current. Excellent line and load regulation specifications. Integrated 150kHz fixed-frequency internal oscillator. Specifications: Parameter Value Output Voltage (Fixed) 12 V Output Current (Maximum) 3 A Input Voltage Range (Maximum) 40 V Switching Frequency 150 kHz Tolerance Over Line and Load ±4% Quiescent Current (Typical) 80 μA Operating Junction Temperature -40°C to +125°C Package Type TO-220-5L Foot Print: Applications: High-efficiency step-down (buck) power conversion. Simple switching regulator circuits for various appliances. On-card switching regulators to step down local supply rails. Providing a stable 12V regulated supply from a higher voltage bus. Battery chargers and pre-regulators. Package Include: 1x LM2596T-12 Buck Fixed 40V 12V 3A TO-220-5L DC-DC Converters DIP IC Datasheet: LM2596T-12
