The RTQ2822AGQVF from RICHTEK is a high-performance, synchronous step-down converter designed for applications requiring up to 12A of output current. It operates within an input supply voltage range of 4.5V to 17V.
This converter integrates low Rds(on) power MOSFETs and an accurate 0.6V reference, contributing to a compact solution. It utilizes the Advanced Constant On-Time (ACOT®) control architecture, which provides fast transient response and reduces the need for external components. The device supports selectable switching frequencies of 400kHz, 800kHz, or 1200kHz, and offers adjustable output voltage from 0.6V to 5.5V.
Key features include a programmable soft-start time, power good indicator, and comprehensive protection features such as cycle-by-cycle current limit, OVP, UVP, input UVLO, and OTP. The RTQ2822AGQVF is available in a thermally enhanced VQFN-18L 3.5x3.5 (FC) package, suitable for surface mount applications.
Applications for this device include server, storage, and network equipment, telecom infrastructure, point of load power modules, high-density DC-DC converters, and high-end digital TVs.
