Package: 56-Lead WQFN Type

Manufacturer: Richtek ( https://www.richtek.com/ )

RICHTEK RT8885AZQW QFN IC

RT8885A

RT8885A

Description

The RT8885A is a dual output 3-phase + 2-phase PWM controller with 3 integrated MOSFET gate drivers and a single SVID interface for CPU and GPU core power supply. This part complies with Intel VR12/IMVP7 Pulse Width Modulation Specification. The RT8885A adopts G-NAVPTM (Green-Native AVP), which is a Richtek proprietary topology derived from finite DC gain compensator in constant on-time control mode. G-NAVPTM makes this part an easy-setting PWM controller to meet all Intel mobile CPU/GPU AVP (Active Voltage Positioning) requirements.

Power Management Control Chip :

1. 12V Power Supply Voltage
2.  2 Phase Power Conversion
3.  Embedded 12V Boot Strapped Driver
4. Precise Core Voltage Regulation
5.  Low Side MOSFET RDS(ON) Current Sensing for Power Stage Current Balance
6.  External Compensation
7.  Adjustable Soft-Start
8.  Adjustable Frequency and Typical at 300kHz Per  Phase
9.  Power Good Indication
10.  Adjustable Over Current Protection
11.  External Reference Voltage Tracking (RT8805CxQVA)
12. – Small 16-Lead and 24-Lead VQFN Packages
13. RoHS Compliant and 100% Lead (Pb)-Free

Applications:

1. IMVP7 Intel CPU/CPU Core Power Supply
