RTQ2183-QA Datasheet | Richtek

5.5V, 3A, 2.4MHz, Automotive Synchronous Buck Converter 1 General Description The RTQ2183-QA is a synchronous buck converter designed to operate within an input voltage range of 2.5V to 5.5V. It delivers up to 3A output current and supports an adjustable output voltage ranging from 0.6V to 3.3V. Utilizing Advanced Constant On-Time (ACOT® ) control architecture, the RTQ2183-QA achieves fast and stable output voltage regulation, making it ideal for applications with dynamic load requirements. By minimizing the number of external ponents, The ACOT® architecture minimizes the number of required external ponents, simplifying design and reducing system cost for efficient power management. Key Features include an independent enable control input and a power-good indicator for easy sequence control. A programmable soft-start function, implemented via an external capacitor on the SS pin, ensures controlled inrush current and smooth powerup. The RTQ2183-QA provides prehensive protection functions, including input undervoltage-lockout, output undervoltage protection, output overvoltage protection, overcurrent protection, and over-temperature protection. Cycle-by-cycle current-limit protection safeguards against shorted outputs. The RTQ2183QA is available in a pact WET-VDFN-8J2L 2x1.5 (FC) package, providing flexibility and space-saving advantages for various system designs.
