ISL91211BIKZ-T集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

特性 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
