Overview

Intersil's ISL85403 Synchronous Buck or Boost Buck Converter is an 36V, 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 36V. 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 in low input voltage conditions. The ISL85403 has a flexible selection of operation modes of forced PWM mode and PFM mode. In PFM mode, the quiescent input current is as low as 180A (AUXVCC connected to VOUT). The load boundary between PFM and PWM can be programmed to cover wide applications.
