有关 ISL91211A 的资源
描述
The ISL91211A is a 4-phase, three-output programmable Power Management IC (PMIC), and the ISL91211B is a 4‑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. It features four buck controllers and can 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 a small solution size. ISL91211A and ISL91211B 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 ISL91211A and ISL91211B deliver a highly robust power solution by featuring a controller based on Renesas' proprietary R5 Technology that 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, ISL91211A and ISL91211B also feature four MPIOs and three GPIOs capable of supporting SPI, I2C communication protocol, and various other pin mode functions.
