The RT7250BZSP is a SOP-8 RoHS DC-DC converter manufactured by Richtek. It is the high-power version of the RT7250, designed to provide an efficient, reliable, and cost-effective DC-DC conversion solution. This regulator utilizes a synchronous buck-converter topology to ensure stable output voltage and current, and an integrated MOSFET for higher current capability. It supports input voltages of 4V to 18V, has a 3A constant output current, and a 3.3V fixed-output voltage. This regulator also includes built-in pre-bias protection, ESD and other over-voltage protection, and soft-start circuitry for smoother operation. It is a great choice for applications such as medical equipment, communications systems, or battery powered devices.
