ISL91211AIK集成電路（IC）的DCDC開關穩(wěn)壓器規(guī)格書PDF中文資料

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
