2.5A Regulator with Integrated High-Side MOSFET for Synchronous Buck or Boost Buck Converter

The ISL85403 is a 40V, 2.5A synchronous buck or boost buck controller with a high-side MOSFET and low-side driver integrated. In buck mode, the ISL85403 supports a wide input range of 3V to 40V. In boost-buck mode, the input range can be extended down to 2.5V and output regulation can be maintained • Buck mode: input voltage range 3V to 40V \n• Boost mode expands operating input voltage lower than 2.5V \n• Selectable forced PWM mode or PFM mode \n• 300μA IC quiescent current (PFM, no load); 180μA input quiescent current (PFM, no load, VOUT tied to AUXVCC) \n• Less than 5μA (MAX) shutdown input;
