Rev.1.00
May 8, 2017 Triple/Quad Output Power Management IC
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, in a wide range of applications where high output
power and small solution size are needed.
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 Intersil’s proprietary R5 Technology, it provides tight output
accuracy and load regulation, ultra-fast transient response, …
