概览

ADP3211 是一款高能效、单相同步降压开关稳压器控制器。 ADP3211 配有集成驱动器，适合用于将笔记本电脑电池电压转换为高性能英特尔芯片组所需的电源电压。 内部 7 位 DAC 用于直接从芯片组或 CPU 读取 VID 代码，并将 GMCH 渲染电压或 CPU 核心电压设置为 0 V 到 1.5 V 范围内的某个值。

  • Notebook power supplies for next generation Intel® Chipsets.
  • Intel® netbook Atom processors.

  • Single-chip solution. Fully compatible with the Intel® IMVP-6.5 CPU and GMCH chipset voltage regulator specifications integrated MOSFET drivers.
  • Input voltage range of 3.3V to 22V.
  • ±7mV worst-case differentially sensed core voltage error overtemperature.
  • Automatic power-saving modes maximizes efficiency during light load operation.
  • Soft transient control reduces inrush current and audio noise.
  • Independent current limit and load line setting inputs for additional design flexibility.
  • Built-in power-good masking supports voltage identification (VID) OTF transients.
  • 7-bit, digitally programmable DAC with 0V to 1.5V output.
  • Short-circuit protection.
  • Current monitor output signal.
  • This is a Pb-free device. Fully RoHS compliant and 32-lead QFN.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
