[原创] Renesas ISL68301PMBus兼容单相数字DC－DC控制方案

Renesas公司的ISL68301是用于SPS和DrMOS功率级的PMBus兼容的单相数字DC/DC控制器,支持广泛的故障管理系统,采用专有硬件支持逐个周期过流,过压,欠压和温度故障.具有独到的无补偿设计,经常是稳定的,输入电压范围:4.75V-16V或4.5V-5.5V,输出电压0.45V-5.5V,输出电压精度0.5%,开关频率200kHz到1.0MHz,主要用在服务器和存储设备,通信和数据通信设备,以及如FPGA,ASIC,DSP和存储器电源.本文介绍了ISL68301主要特性,框图,几种应用电路,以及评估板ISL68301EVAL2Z主要特性和指标,电路图,材料清单和PCB设计图.

The ISL68301 is a PMBus compliant, single-phasedigital DC/DC controller for use with SPS and DrMOSpower stages.

The ISL68301 implements the Renesas fully digitalChargeMode™ control modulation scheme, allowing itto achieve both industry leading performance and ease ofuse. ChargeMode control provides an inherently stablecontrol loop that can respond to load transients in a singleswitching cycle, significantly decreasing output capacitorrequirements.
