LM2596HVS DCDC Step Down Power Module 4.550V to 335V Adjustable Buck Converter Efficiency

LM2596HVS DCDC Adjustable StepDown Module Key benefits Reliable stepdown conversion for a wide range of input voltages, enabling stable power for electronics and projects. efficiency up to 92%, reducing heat and improving battery runtime. Compact size for easy integration into prototypes, control panels, and equipment. Main features Chip: LM2596HVS (this module uses LM2596HVS, not LM2596S) Input voltage range: DC 4.5 V to 50 V Output voltage range: DC 3 V to 40 V, continuously adjustable Maximum output current: 3 A Conversion efficiency: up to 92% Output ripple: less than 30 mV Switching frequency: 150 kHz Operating temperature: 45 to +85 degrees C Module size: 43 mm x 21 mm x 14 mm (L x W x H) Terminals labeled for easy connection: IN+, IN, OUT+, OUT Performance notes and limitations This is a stepdown (buck) regulator only. The input voltage must be at least 1.5 V higher than the desired output voltage. The module cannot boost voltage. For continuous operation above 2.5 A or continuous output power greater than 10 W, add a heatsink to improve thermal performance. Measured example: with 12 V input and 5 V output at 1 A load, load regulation is less than 1%. Typical applications Converting 12 V or 24 V vehicle or battery sources to lower voltages for electronics Bench power supplies and lab use for powering microcontrollers, sensors, and modules Industrial control circuits and embedded systems that require adjustable regulated rails Why choose this module Wide input range lets you use common batteries and power supplies without extra converters. efficiency helps keep temperature and power loss low in compact installations. Small footprint and clear terminal labeling simplify mounting and wiring. Installation tips Verify input voltage is sufficiently higher than the target output by at least 1.5 V. Adjust output voltage using the onboard potentiometer while monitoring with a meter before connecting sensitive loads. Secure module to a stable surface and provide airflow or a heatsink for current use. What is included One LM2596HVS adjustable stepdown module, ready for wiring and adjustment.
