Features

  • Triple output 2+1+1 phases (ISL91211AIK) or quad output, four single phases (ISL91211BIK).
  • 2.7V to 5.5V supply voltage.
  • 5A per phase peak current capability.
  • Small solution size (for four phase design).
  • High efficiency (92.2%, L = 220nH for 3.8VIN/1.8VOUT).
  • Low IQ in low power mode.
  • Proprietary control scheme reduces output capacitor and supports fast load transient (such as >50A/µs per phase).
  • ±0.7% system accuracy, remote.

Datasheet ISL91211AIK, ISL91211BIK Triple/Quad Output Power Management IC for Industrial and Computing Applications The ISL91211AIK is a 4-phase, three output programmable Power Management IC (PMIC) and the ISL91211BIK is a 4-phase, four output programmable PMIC. Optimized with highly efficient synchronous buck converters for multiphase and single-phase operations, these converters deliver up to 5A per phase maximum output current. Featuring four buck controllers that can reconfigure their power stages to the controllers, both PMICs offer flexibility and allow seamless, design-in for a wide range of applications that need high output power and a small solution size.
