Renesas Electronics Corporation Quad Output Power Management IC ISL91212BIIZ-TR5772

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. 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 Skipping modes under light-load conditions to further improve efficiency and maximize battery life. These PMICs deliver highly robust power solutions by using a controller based on Intersil’s proprietary R5 Technology, which provides tight output accuracy and load regulation, ultra-fast transient response, seamless DCM/CCM transitions, and require no external compensation. In addition to the standard interrupt, chip enable, and watchdog reset functions, these ISL91212 PMICs feature three MPIOs and two GPIOs capable of supporting I2C communication and various other pin mode functions.
