Resources for ISL91212B
Description
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.
