[原创] NXP PF4210用于i．MX 8MMCU的14路功率管理方案

NXP公司的PF4210是14路功率管理集成电路(PMIC),具有全集成的功率器件和最少外接元件的高度可编程/可配置架构,有多达6个降压转换器,6个线性稳压器和RTC电源和一个扣式电池充电器,为应用处理器,存储器,系统外设等在各种应用提供完整的电源系统.输入电压2.8 V-4.5 V,采用OTP作为器件配置,主要用在OTT STB,无线音频,语音识别辅助,条形音箱,A/V接收机以及通用嵌入式.本文介绍了PF4210主要特性和优势,框图和应用框图,以及评估板KITPF4210EPEVB主要特性和电路图.

14-channel Power Management Integrated Circuit (PMIC) for audio/video applications The PF4210 high performance power management integrated circuit (PMIC) provides a highly programmable/configurable architecture with fully integrated power devices and minimal external components. With up to six buck converters, six linear regulators,an RTC supply, and a coin cell charger, the PF4210 can provide power for a complete system, including applications processors, memory, and system peripherals, in a wide range of applications.

With on-chip one-time programmable (OTP) memory, the PF4210 is available in preprogrammed standard version or nonprogrammed to support custom programming.The PF4210 is defined to power low-cost audio/video applications using the i.MX 8M family of applications processors.

PF4210主要特性和优势:

• Four to six buck converters, depending on configuration..
