RTQ8826
Single Rail 6-Phase PWM Controller with PMBus
General Description
The RTQ8826 is a 6/5/4/3/2/1 phase synchronous buck controller. The RTQ8826 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 G-NAVPTM topology, the RTQ8826 features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RTQ8826 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.
