RT6258BGQUF Description

Short technical summary and product information.

The RT6258BGQUF from Richtek is a power management IC combining a synchronous step-down (buck) converter and a linear (LDO) regulator in a single device. The buck converter supports an input voltage up to 23V and delivers up to 8A of output current, making it suitable for high-current point-of-load applications. The integrated LDO provides a second regulated output for noise-sensitive circuits.

Operating at a fixed switching frequency of 500kHz, the buck converter enables a balance between efficiency and external component size. The synchronous rectification topology improves efficiency by replacing the freewheeling diode with a low-resistance MOSFET.

The device is housed in a compact UQFN-12H(FC) package, which is optimized for space-constrained designs. This package type supports surface-mount assembly and offers good thermal performance for the rated output current.
