Brand , DCDC LM2596 StepDown Power Module Key benefits Reliable voltage reduction: Converts a higher DC input to a lower, stable DC output so sensitive electronics run safely. Wide compatibility: Accepts 4–40 VDC input, allowing use with many common DC power sources without extra converters. Spacesaving form factor: Compact dimensions (L x W x H = 6.7 x 3.5 x 1.2 cm approx.) make it easy to fit into enclosures and projects. Practical and easy to integrate: Designed for direct use in electronic projects, prototypes, and repairs where a steppeddown DC supply is required. What it does DCDC LM2596 stepdown (buck) regulator module that reduces input DC voltage to a lower DC voltage suitable for downstream devices, providing a stable supply and protecting circuits from overvoltage conditions. Important attributes Model/type: LM2596 stepdown power module. Input voltage range: 4–40 VDC (specified). Size: Approximately 6.7 x 3.5 x 1.2 cm (L x W x H). Condition: Brand , . Typical use scenarios Electronics projects and prototypes: Provide a stable lowervoltage supply from bench power supplies, battery packs, or adapters within the 4–40 VDC input range. Automotive and mobile projects: Power sensitive modules or control boards from vehicle or marine DC systems (within the specified input range) without needing a separate dedicated regulator. Renewable and battery systems: Step down voltage from solar panels or highervoltage battery banks to feed lowervoltage sensors, controllers, or lighting. Notes for integration Confirm your required output voltage and load requirements before use; this module is a stepdown regulator intended to reduce input DC voltage within the specified range. Verify wiring and mounting fit given the module's compact size (6.7 x 3.5 x 1.2 cm approx.). Package: Brand LM2596 DCDC stepdown power module (as specified above).
