LM2596 DC-DC Buck Converter Adjustable Step Down Power Supply Module

LM2596 DC-DC Buck Converter Adjustable Step Down Power Supply Module is an buck converter step-down power module with high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Freeduino, UNO, other main boards and basic modules. When the output current keeps greater than 2.5 A (or output power greater than 10W), please add a heat sink on it.

This device is internally compensated to minimize the number of external components to simplify the power supply design.

Features:

• Input voltage:3-40V
• Output voltage:1.5-35V(Adjustable)
• Output current: Rated current is 2A, maximum 3A(Additional heatsink is required)
• Module Properties: non-isolated constant voltage module
• Rectification: non-synchronous rectification
• Short circuit protection: current limiting, since the recovery
