RTQ2134-QA Datasheet | Richtek

Description The RTQ2134-QA is a multi-phase, programmable power management IC that integrates with four high-efficient, synchronous buck converter cores. The RTQ2134-QA 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-QA 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-QA also supports remote-sense function to get accurate output voltage at large loading. Moreover, the device has interrupt and fault-detection functions to report error status. The RTQ2134-QA is available in a WET-WQFN-30L 4.5x5 (FC) package. 2 Applications - Automotive Systems 3 Features - FMEA pliant Pinout - AEC-Q100 Grade1 Qualified - 2 + 2/2 + 1 + 1 Phase Output - I2C Programmable Output Voltage: 0.3V to 1.85V - Maximum Output Current: Total 20A, 5.5A per Phase - Output Remote Sense - Fast Transient Response - Input Supply Voltage Range: 3V to 6V - Selectable Automatic Phase Shielding and Power Saving Mode Enables Higher Light Load Efficiency - Dynamic Voltage Scaling (DVS) with Programmable Slew Rate for Each Output - Programmable Soft-Start Function - Interrupt Function and Fault Detection - Watchdog Function - Input Undervoltage-Lockout (UVLO) - Cycle by Cycle Current Limit - Output Undervoltage Protection - Over-Temperature Protection - WET-WQFN-30L 4.5x5 (FC) - Junction Temperature Range: - 40C to 150C 4 Simplified Application Circuit VIN CIN I2C Signal Signal Input Signal Output AVIN VOUT1 PVIN1 LX1 PVIN2 LX4 PVIN3 RTN1 PVIN4 VOUT2 EN SCL RTQ2134-QA...
