  • Configurable Output Voltage (VOUT) via the FB Pin
  • 1A Max Output Current (IOUT)
  • 500kHz/750kHz Selectable Switching Frequency (fSW)
  • Output Over-Voltage Protection (OVP) and Short-Circuit Protection (SCP) with Hiccup Mode
  • Over-Temperature Warning (OTW) and Shutdown
  • I2C Interface with ALT Pin
  • One-Time Programmable (OTP) NonVolatile Memory (NVM)
  • I2C-Configurable Pulse-Frequency Modulation (PFM)/Pulse-Width Modulation (PWM) Mode, Soft Start, Over-Current Protection (OCP), and OVP

Applications

  • Buck-Boost Bus Supplies
