General Description

The RTQ8825 is a dual output voltage rail 3+2-phase controller: a 3/2/1/0 phase synchronous buck controller, the rail A and a 2/1/0 phase synchronous buck controller, the rail B.

The RTQ8825 adopts G-NAVPTM (Green Native AVP) which is Richtek’s proprietary topology derived from finite DC gain of EA amplifier with current mode control, making it easy to set the droop to support all CPU/Microprocessor requirements of AVP (Adaptive Voltage Positioning).

Based on the GNAVPTM topology, the RTQ8825

Overview

RTQ8825 Dual Rail 3+2-Phase PWM Controller with PMBus General.

Key Features

  • a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RTQ8825 supports VID on-the-fly function with four different slew rates via PMBus command setting. The DAC converts the VOUT_COMMAND code ranging from 0.25V to 1.516V with 1.953mV per step. The RTQ8825 integrates a high accuracy ADC for platform and function settings, such as SPS type, PMBus address, boot voltage and load-line. The RTQ882.
