MT3608

The MT3608 is a step-up boost converter from Aerosemi Technology Co., Ltd (Xi'an, China), specified in the manufacturer's datasheet Rev3.0 with a 2V to 24V input range, 1.2MHz switching frequency, a 0.6V feedback reference and a 4A switch peak current limit, supplied in SOT-23-6 with the top marking B628. It raises a low input rail to a higher regulated output for battery-powered devices, LED backlighting and auxiliary supplies in portable equipment, using a small external inductor and diode. Buyers must weigh one sourcing risk before ordering: MT3608B parts and clone parts from other manufacturers circulate with the same B628 top marking, and the marking alone cannot prove that a part is genuine Aerosemi - verify the source through the original manufacturer or an authorised channel before committing a production buy. Selection advice: design and qualify strictly against the Aerosemi Rev3.0 datasheet for this code, and state the required provenance in your RFQ so the offered lot can be checked. Parameters verified against Aerosemi documentation.
