Présentation
Description
RT9119GQV is a Richtek buck regulator IC. It’s a synchronous step-down DC-DC converter in a compact QFN package, designed to take a higher input voltage and generate a lower, stable output via an external resistor network. Key traits typically include PWM/PFM operation for high efficiency, soft-start, an enable/shutdown pin, and protective features such as overcurrent, overtemperature, UVLO, and short-circuit protection. It’s aimed at portable/embedded applications to generate core or other rails, in devices like smartphones, tablets, wearables, and small motherboards. The “GQV” suffix denotes the specific package/pinout variant and qualification. For exact specifications (input voltage range, output voltage options, current capability, switching frequency), consult the RT9119GQV datasheet or product page. If you share your target input/output, I can point to the relevant specs.
