DSQ2134-QA-02 May 2022 www.richtek.com 1 2.1MHz, 20A Multi-Phase Step-Down Converter with I2C Interface General Description The RTQ2134 is a multi-phase, programmable power management IC that integrates with four high efficient, synchronous step-down converter cores. The RTQ2134 can be 2 + 2 and 2 + 1 + 1 output by OTP. It also features wide output voltage range and the capability to configure the corresponding power stages, which make the device optimized to meet power management requirements for low-power processors, such as core power for CPUs and GPUs. The RTQ2134 supports many programmable functions including voltage level, slew rate of voltage change, and slew rate of soft-start via an I2C interface capable of operating up to 3.4MHz. The RTQ2134 also supports remote-sense function to get accurate output voltage at large loading. Moreover, the device has interrupt and fault-detection function to report error status. The RTQ2134 is available in a WET-WQFN-30L 4.5x5 (FC) package.
