RAA228228GNP - Digital Double Output 20-Phase PWM Controller with Adaptive Voltage Scaling Bus (AVSBus)

Product Description

RAA228228GNP is a digital double output 20-phase (X+Y ≤ 20) PWM controller with an Adaptive Voltage Scaling Bus (AVSBus) interface. It can be configured to support any required phase assignment up to a maximum of 20 phases across the two outputs (X+Y). The RAA228228 AVSBus interface complements PMBus by providing a common high-speed interface that accelerates point-to-point communication. 

Product Features

Flexible phase assignment from 0 to 20 phases per output

Up to 2MHz switching frequency operation for high density designs

Differential remote voltage sensing supports ±0.5% closed-loop system accuracy over load, line, and temperature

Highly accurate current sensing for excellent load line regulation and accurate OCP

Supports the full range of Renesas Smart Power Stage (SPS) devices

Comprehensive fault management enables high reliability systems

Intuitive configuration using PowerNavigator

SMBus/PMBus V1.3 and AVSBus compatible

Up to 16 user configurations stored in device Non-Volatile Memory (NVM)

Applications

Artificial Intelligence/accelerator cards (FPGA, ASIC)

Network equipment

Server/storage equipment

Telecom/datacom equipment

Point-of-load power supply (DSP, ASIC, FPGA)

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
