ISL78201
40V 2.5A Regulator with Integrated High-Side MOSFET for Synchronous Buck or Boost Buck Converter
FN8615 Rev 2.00 August 15, 2016
The ISL78201 is an AEC-Q100 qualified 40V, 2.5A synchronous buck or boost buck controller with a high-side MOSFET and low-side driver integrated. In Buck mode, the ISL78201 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 when VIN drops below VOUT, enabling sensitive electronics to remain on during cold-cranking and start-stop applications.
The ISL78201 has a flexible selection of operation modes including forced PWM mode and an optional switch to PFM mode for light loads.
