The ISL95872 is a Single-Phase Synchronous-Buck PWM
controller featuring Intersil’s proprietary R4™ Technology. The
R4™ modulator has integrated compensation, fast transient
performance, accurate switching frequency control, and
excellent light-load efficiency. These technology advances,
together with integrated MOSFET drivers and a schottky
bootstrap diode, allow for a high performance regulator that is
highly compact and needs few external components.
Differential remote sensing of the output voltage is an
additional 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.
