Description
The ISL95873 is a Single-Phase Synchronous-Buck PWM controller featuring Renesas' 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 ISL95873 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 soft-start. When the external reference level meets the internal reference voltage, the ISL95873 switches from the external reference to the internal reference. The external reference is only used during soft-start.
