The LM2596 DC-DC Adjustable Buck Converter Module converts high DC input to a lower, stable output. With an input range of 4.5V to 40V, this step-down module provides 1.23V to 37V. It supplies up to 3A for various electronic prototyping projects.
Key Features
- Output Adjustment: Multi-turn potentiometer varies voltage from 1.23V to 37V. Manual tuning prevents component damage from incorrect voltage levels.
- Internal Protection: Integrated thermal shutdown and current limit hardware. Stops permanent damage during high-load circuit faults.
- Operational Efficiency: 150kHz switching frequency achieves 92% energy conversion. Limits waste heat during continuous use in poorly ventilated enclosures.
- Signal Stability: Output ripple remains under 30mV during operation. Maintains steady logic levels for microcontrollers and digital sensors.
Frequently Asked Questions
Can LM2596 be used as a battery charger?
This module lacks the constant current logic required for safe lithium charging. It works for fixed-voltage power supply needs only.
Does LM2596 need a heatsink for 3A?
Continuous 3A output triggers thermal shutdown without external cooling. Add a heatsink when operating in high humidity or cramped spaces.
