ISL91212BIIZ-TR5775

ISL91212BIIZ-TR5775 is a 4-phase, four output programmable PMIC. It is 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 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. This ISL91212 PMIC integrates low ON-resistance MOSFETs and programmable PWM frequency, allowing the use of very small external inductors and capacitors. It features automatic diode emulation and pulse skipping modes under light-load conditions to further improve efficiency and maximize battery life. Applications include FPGA power, industrial MPU power, human machine interface, optical transceivers, SSD.
