Nov 6, 2017 Triple/Quad Output Power Management ICs
The ISL91212AR5770 is a 4-phase, three output
programmable Power Management IC (PMIC) and the
ISL91212BR5771, ISL91212BR5769,
ISL91212BR5775, and ISL91212BR5772 are 4-phase,
four output programmable PMICs. 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
requiring high output power and small solution size. Features Triple output 2+1+1 phases (ISL91212AR5770) or
quad output single phase (ISL91212BR5771,
ISL91212BR5769, ISL91212BR5775, and
ISL91212BR5772) 2.5V to 5.5V supply voltage 5A per phase output current capability Small solution size (7x10mm2 for four phase design) High efficiency (94.7% for 3.8VIN/1.8VOUT) Low IQ in low power mode These ISL91212 PMICs 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 …
