Mini DC-DC Boost Converter Step Up Module 2.7V to 11V Voltage Regulator Short-Circuit&Overtemp Protection Booster Power Module

Features:1. This module supports an input voltage range of 2.7V to 11V, suitable for diverse power supply applications2. Utilises an aluminium substrate for superior heat dissipation, facilitating the addition of heat sinks for enhanced efficiency3. Selectable output voltages of 5V or 12V provide appropriate power supply for different devices4. Incorporates built-in short-circuit protection to ensure safety for both the module and connected devices under abnormal conditions5. Compact design facilitates integration into diverse electronic devices, optimising space utilisationSpecifications:Operating Voltage: DC 2.7–11VOutput Voltage: DC 5V/12V (optional)Frequency: 500K–1MHzOperating Temperature: -40°C to +125°CFunction1. Input/output with TVS protection2. Output short-circuit protection3. Built-in over-temperature protection4. Default PFM low-power modeImportant Notes:1. The module cannot deliver full output power at excessively low input voltages, particularly noticeable below 3V. Users requiring higher power output should take note.2. The module's maximum 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 maximum 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 operation is PFM mode, though users may adjust settings independently.Package list:Module ×1
