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.
