• Two Highly Efficient Programmable Buck Regulators
  • Integrated FETs with Low R_DSON
  • Bucks Operate with Their Phases Shifted to Reduce
    the Input Current Ripple and Capacitor Size
  • Programmable Output Voltage via the SPI interface
  • Overvoltage and Undervoltage Lockout
  • Automatic Internal Soft Start with Power-on Reset
  • PFM Mode for Low-Load, High-Efficiency Operation
• Low-Dropout LDO 3.0V, 250 mA
• SPI-Programmable Interrupt Comparator (2.0V to 4.0V) to
  Monitor VIN
