ISL91212A, ISL91212B

Triple/Quad Output PMIC with I2C Interface

DATASHEET

Add

The ISL91212A is a four-phase, three output

programmable Power Management IC (PMIC) and the

ISL91212B is a four-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. They feature four buck

controllers and can reconfigure their 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.

The ISL91212A and ISL91212B 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 ISL91212A and ISL91212B deliver a

highly robust power solution by featuring a controller

based on the proprietary Renesas R5 Technology, which

provides tight output accuracy and load regulation,

ultra-fast transient response, seamless DCM/CCM

transitions, and requires no external compensation.

In addition to standard interrupt and chip enable functions,

the ISL91212A and ISL91212B feature three MPIOs and

two GPIOs capable of supporting the I2C communication

protocol and various other pin mode functions.
