diymore JW3510 Isolated Power Module DC-DC Converter: 3-42V Input to 5/12V Output Buck-Boost Module Reserved for LDO

ParameterInput Voltage: DC 3-42VOutput Voltage: DC 5V, DC 12VProduct DescriptionThis flyback isolated module features a wide 3-42V input voltage range, capable of step-up or step-down conversion to 5V/12V outputs. Includes built-in output short-circuit protection to prevent module burnout. Reserved LD0 pads for AMS1117 series and 78L05 series regulators, suitable for applications requiring more stable LD0 outputs. When paired with an LD0 regulator, it can also output 3.3V/1.8V to power low-voltage devices like microcontrollers. The module features a half-hole gold-plated design. To facilitate LD0 pad reservation during PCB layout, users may cutout the LD0 soldering area on the board's underside.Important Notes1. When input voltage exceeds 28V, exercise extreme caution regarding thermal shock risks during powered-on startup. Mechanical switches may generate transient voltage spikes exceeding twice the supply voltage during switching, posing a risk of module damage. Avoid powering up with a load directly connected.2. This module features output overload protection. When the load exceeds the rated range, the system will automatically shut off the output. At this point, the measured output voltage will be 0V, indicating a normal protective state. The module is not damaged in this situation and will resume normal operation once the overload is removed. Customers can use it with confidence.Package includeModule*1
