“Smartphone and tablet application processors require smaller footprint power supplies and higher output current and efficiency to maximize battery life,” said Mark Downing, Vice President, Core Power Solutions Division, Renesas Electronics Corporation. “The ISL91302B and ISL91301A/B PMICs offer designers everything they need to solve their toughest PCB layout challenges, dynamically scale performance, and extend battery run-time.”

Key Features of ISL91302B PMIC

  • Available in three factory configurable options for one or two output rails:
    • Dual-phase (2 + 2) configuration supporting 10A from each output
    • Triple-phase (3 + 1) configuration supporting 15A from one output and 5A from the second output
    • Quad-phase (4 + 0) configuration supporting 20A from one output
  • Small solution size: 7mm x 10mm for 4-phase design
  • Input supply voltage range of 2.5V to 5.5V
  • I2C or SPI programmable Vout from 0.3V to 2V
  • R5 modulator architecture balances current loads with smooth phase adding and dropping for power efficiency optimization
  • Provides 75μA quiescent current in discontinuous current mode (DCM)
  • Independent dynamic voltage scaling for each output
  • ±0.7percent system accuracy for -10°C to 85°C with remote voltage sensing
  • Integrated telemetry ADC senses phase currents, output current, input/output voltages, and die temperature, enabling PMIC diagnostics during operation
  • Soft-start and fault protection against under voltage (UV), over voltage (OV), over current (OC), over temperature (OT), and short circuit
