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 highly robust power solution by featuring a controller based on the Renesas proprietary R5 Technology. The controller provides tight output accuracy and load regulation, ultra-fast transient response, seamless DCM/CCM transitions, and requires no external compensation. In addition to the standard interrupt, chip enable, and watchdog reset functions, the ISL91301A and ISL91301B also feature four MPIOs and two GPIOs capable of supporting SPI, I2C communication protocol, and various other pin mode functions.
