Rev. 2.00
Apr 6, 2018 Triple/Quad Output Power Management IC The ISL91301A is a 4-phase, three output programmable
Power Management IC (PMIC) and the ISL91301B is a
4-phase, four output programmable PMIC. They are
optimized with highly efficient, synchronous buck
converters capable of multiphase and single-phase
operations. The devices can deliver 4A per phase
continuous output current for 2.8V to 5.5V supply
voltages or 3A per phase current for wider 2.5V to 5.5V
supply voltages. 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.
The ISL91301A and ISL91301B 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 ISL91301A and ISL91301B deliver a …
