ISL91211A, ISL91211B

Triple/Quad Output PMIC with SPI/I2C Interface

DATASHEET

The ISL91211A is a 4-phase, three output programmable

Power Management IC (PMIC) and the ISL91211B is a

4-phase, four output programmable PMIC. They are

optimized with highly efficient synchronous buck

converters capable of multiphase and single-phase

operations that can deliver up to 5A per phase continuous

output current. It features four buck controllers and has the

capability to reconfigure its power stages to these

controllers. This flexibility allows seamless design-in for a

wide range of applications that require high output power

and small solution size.

ISL91211A and ISL91211B integrate low ON-resistance

MOSFETs and programmable PWM frequency, allowing the

use of very small external inductors and capacitors. They

feature automatic Diode Emulation and Pulse Skipping

modes under light-load conditions to further improve

efficiency and maximize battery life. The ISL91211A and

ISL91211B deliver a highly robust power solution by

featuring a controller based on the Renesas proprietary R5

Technology that provides tight output accuracy and load

regulation, ultra-fast transient response, seamless DCM/CCM

transitions, and requires no external compensation.

In addition to the standard interrupt, chip enable, and

watchdog reset functions, ISL91211A and ISL91211B also

feature four MPIOs and three GPIOs capable of supporting

SPI, I2C communication protocol, and various other pin

mode functions.

Applications

• Smartphones, AR/VR Glasses, Drones

• Optical Transceiver Modules

• Artificial Intelligence (AI) Processors
