Features

• Triple output 2+1+1 phases (ISL91211AIK) or quad

output, four single phases (ISL91211BIK)

• 2.7V to 5.5V supply voltage

• 5A per phase peak current capability

• Small solution size (for four phase design)

• High efficiency (92.2, L = 220nH for

3.8VIN/1.8VOUT)

• Low IQ in low power mode

• Proprietary control scheme reduces output

capacitor and supports fast load transient (such as

>50A/μs per phase)

• ±0.7 system accuracy, remote voltage sensing

• I2C programmable output from 0.3V to 2V

• Independent Dynamic Voltage Scaling (DVS) for

each output

• Soft-start and fault detection (UV, OV, OC, OT),

short-circuit protection

• 4.70mmx6.30mm 35 ball BGA with 0.8mm pitch

Applications

• Industrial controls and FPGAs

• Computing servers and systems

• Home gateways and appliances

ISL91211AIK属于集成电路（IC） > DC DC 开关稳压器。瑞萨科技有限公司制造生产的ISL91211AIK稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
