The SGM61620 is a fully-integrated, synchronous, rectified, Buck converter. It offers a very compact solution to provide a 2A continuous current over a wide input voltage range from 4.2V to 60V. Reduced size and cost of over-voltage and surge protection solutions due to input voltage transient tolerances up to 65V.
The SGM61620 features 400kHz operating frequency, which is suitable for high efficiency. Integration and internal compensation eliminates many external components and the pin out is optimized to simplify PCB layout.
The EN pin employs an enable divider to establish a precision threshold that simplifies UVLO adjustment and device on/off control. The power-good output is designed with built-in filtering and delay to provide a true indicator of system status.
The SGM61620A operates in power save mode (PSM), which maintains high efficiency during light load operation.
Protection features include current limit, hiccup mode short-circuit protection and thermal shutdown with auto recovery.
The SGM61620 is available in a Green SOIC-8 (Exposed Pad) package.
