  MT3608 2A MAX DC-DC STEP UP POWER MODULE BOOSTER POWER MODULE   DESCRIPTION: This module features the MT3608 2 Amp step up (boost) converter, which can take input voltages as low as 2V and step up the output to as high as 28V. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes under-voltage lockout, current limiting, and thermal overload protection.This module has a multi-turn trimpot (potentiometer) that you can use to adjust the output voltage. Since the trimpot has 25 turns of adjustment you can easily adjust the output of the module to exactly the voltage you need.Boost converters are a great way to easily increase a given voltage, but that boost comes at the cost of less output current compared to input current. Since this is a boost converter the output voltage has to be higher than the supplied input voltage.   SPECIFICATIONS:   Maximum output current: 2A Input voltage: 2V ~ 24V Maximum output voltage: > 28V Adjustment 25 turn trimpot Efficiency: > 93% PACKAGE INCLUDE: 1x MT3608 DC-DC Step up converter
