Description: The module uses domestic high-quality LM2596 chip, high efficiency (up to 92%), at the same time small heat, can easily reach more than 3A current,with the TI's op amp control output current, so that the overall output is very stable. This module uses a low ESR filter capacitor, can make the ripple voltage as low as 50mV! This module uses a machine patch and reflow soldering. At the same time, each module undergoes a two-hour aging test before shipment to ensure high reliability. Easy to install,convenient disassembly.Using excellent raw materials, the power consumption is lower. Applications: DIY mobile power supply, vehicle power supply, communication equipment power supply, all kinds of occasions (such as aeromodelling, etc.) which have strict requirements on volume and weight. Specification: Material: PCB Board Size: 5cm/1.97inch Module Properties: Non-Isolated Buck Module Rectification: Non-synchronous rectification Input voltage: 7V-35V Output voltage: 1.25V-30V Output current: adjustable up to 3A Conversion efficiency: 92% (highest) Switching frequency: 150KHz Package Includes: 1 Piece Power Step Down Module Note: Please allow slightly difference due to manual measurement. Color may be slightly different since different monitor
