ISL91211AIK, ISL91211BIK

Triple/Quad Output Power Management IC for Industrial and Computing Applications

Datasheet

The ISL91211AIK is a 4-phase, three output

programmable Power Management IC (PMIC) and

the ISL91211BIK is a 4-phase, four output

programmable PMIC. Optimized with highly efficient

synchronous buck converters for multiphase and

single-phase operations, these converters deliver up

to 5A per phase maximum output current. Featuring

four buck controllers that can reconfigure their power

stages to the controllers, both PMICs offer flexibility

and allow seamless, design-in for a wide range of

applications that need high output power and a small

solution size.

ISL91211AIK and ISL91211BIK integrate low

ON-resistance MOSFETs at 2MHz switching

frequency, allowing smaller external inductors and

capacitors to be used. With automatic Diode

Emulation and Pulse Skipping modes under light-load

conditions, this feature improves efficiency and

maximizes battery life. The ISL91211AIK and

ISL91211BIK deliver a highly robust power solution

through a controller based on the Renesas proprietary

Rapid Robust Ripple Regulator (R5) technology,

offering tight output accuracy and load regulation,

ultra-fast transient response, seamless DCM/CCM

transitions, and no required external compensation.

In addition to the standard interrupt, chip enable, and

watchdog reset functions, the ISL91211AIK and

ISL91211BIK also feature four MPIOs and three

GPIOs that supports SPI, I2C communication

protocol, and various other pin mode functions.

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
