RT7291AGQUF is an integrated multiple-output synchronous buck DC-DC converter with a UQFN-16 RoHS package manufactured by Richtek. It can provide up to 3.3V/1A for microprocessors and other core logic devices as well as 3.3V, 2.5V and 1.8V outputs to support the complete power supplies for high-end systems such as Networking, Storage, Cloud Computing, and extreme gaming. This buck DC-DC converter utilizes an advanced architecture to maintain high power efficiency and excellent load transient performance. The operating input voltage range is from 2.375V to 6V which makes it suitable for application from single-cell Li-ion battery to large voltage supply rails. The RT7291AGQUF also has a 0.45V reference voltage, an internal 65mO/45mO low RDS(ON) MOSFETs for high power efficiency, and a wide PWM frequency up to 1.3MHz. It also has multiple protection functions, including OVP (over voltage protection), UVP (undervoltage protection) and OCP (over current protection). With all these features, RT7291AGQUF can be used in a variety of consumer electronics and industrial applications.
