ISL95872 Datasheet | Renesas

feature . For maximum efficiency, the converter automatically enters diode-emulation mode (DEM) during light-load conditions such as system standby. The ISL95872 accepts a wide 3.3V to 25V input voltage range, making it ideal for systems that run on battery or AC-adapter power sources. It also is a low-cost solution for applications requiring tracking of an external reference voltage during softstart. When the external reference level meets the internal reference voltage, the ISL95872 switches from the external reference to the internal reference. The external reference is only used during soft-start.
