NXP公司的PF5020是多路汽车应用PMIC,它集成了多个高性能降压稳压器,可以作为单独使用的点负载稳压器集成电路(IC),或作为配套芯片形成更大的PMIC.器件内置了一次性编程(OTP)存储器存储了主要起动配置,大大地降低了外接元件.起动后通过高速I2C可调整稳压器参数.PF5020包括了三个高效降压转换器,一个可选择负载开关的线性稳压器.RTC电源和纽扣电池充电器,看门狗计时器/监视器,监测电路以符合ASIL B安全等级,3.4MHz I2C通信接口.主要用在汽车娱乐系统,高端消费类电子和工业应用.本文介绍了PF5020主要特性,内部框图,功能框图和简化应用框图,电压监测架构图以及应用框图,评估板KITPF502XSKTEVM主要特性,电路图,材料清单和PCB设计图.

The PF5020 integrates multiple high performance buck regulators. It can operate as a stand-alone point-of-load regulator IC, or as a companion chip to a larger PMIC.Built-in one-time programmable (OTP) memory stores key startup configurations,drastically reducing external components typically used to set output voltage andsequence of regulators. Regulator parameters are adjustable through high-speed I2C after start up offering flexibility for different system states.

The KITPF502XSKTEVM evaluation board is the socket programming kit of the PF502x family of power management ICs from NXP Semiconductors. This user guide describes the functionality of the evaluation board, explains how to use the PMIC device in an application environment, and gives details about the hardware and software required.
