diymore | DC-DC Mini Boost Module 2.7-11V to 5V 12V 10A Charge/Discharge With Short Circuit Protection Indicator Boost Board

Features1. Supports input voltage range of 2.7V to 11V, suitable for diverse power supply applications2. Utilizes aluminum substrate for superior heat dissipation and easy heatsink attachment, enhancing efficiency3. Selectable output voltage of 5V or 12V to provide optimal power for different devices4. Built-in short-circuit protection mechanism ensures safety for the module and connected devices under abnormal conditions5. Compact design facilitates integration into diverse electronic devices, saving spaceParameterOperating Voltage: DC 2.7-11VOutput Voltage: 5V/12V (selectable)Frequency: 500K-1MHzInput/Output TVS ProtectionOutput Short-Circuit ProtectionBuilt-in Over-Temperature ProtectionDefault PFM Low Power ModeOperating Temperature: -40℃ to +125℃Important Notes1. The module cannot deliver full output power at excessively low input voltages, particularly noticeable below 3V. Users requiring higher output power should take this into consideration.2. The module's MAX switching current is 10A. Users should operate within 9A to allow headroom. Output current is determined by input parameters; input current must not exceed 9A. Calculate efficiency at 70% (allowing headroom). Formula for module MAX output current: out = Vin * 6.3 / Vout3. Shorting the PWM pad adjacent to the output terminals enables PWM mode; disconnecting it activates PFM mode. Default is PFM mode, adjustable by the user.Package includeModule*1 (Model optional)
