SGM61720YPS8G/TR

SGM61720YPS8G/TR is a high efficiency, constant on-time control synchronous buck converter with a wide input voltage range from 6V to 60V. The output voltage is adjustable up to 24V using the internal reference voltage. This device has 2.5A output current capability and operates at an almost fixed quasi-constant frequency (depending on VOUT setting). With light load, the inductor current reaches zero in each cycle and the device shifts into power-save mode in which frequency drops and becomes load dependent to maintain high efficiency. It offers a broad set of features including input under-voltage lockout, internal soft-start, short-circuit protection, current limiting and thermal shutdown. Application includes non-isolated telecommunication buck regulators, secondary high voltage post-regulators, automotive systems, mobile base stations, 48V industrial systems.
