: While the LM2596 chip is technically rated for up to 3A, real-world reports suggest that for sustained loads over 2A, the module requires an external heat sink to prevent thermal throttling or damage.
What is your (e.g., 12V battery, 24V adapter)? What specific device are you trying to power? Hw-133-v1.0 Datasheet
: This design reduces power loss through the diode, contributing to its high 90%+ efficiency rating. Comparison: HW-133 vs. LM2596 : While the LM2596 chip is technically rated
