1 / 32 page 1 DATASHEET Single-Phase R4™ Digital Hybrid PWM Controller with Integrated Driver, PMBus/SMBus/I2C and PFM ISL68200 The ISL68200 is a single-phase synchronous-buck PWM controller featuring Intersil’s proprietary R4™ Technology. It supports a wide 4.5V to 24V input voltage range and a wide 0.5V to 5.5V output range. Integrated LDOs provide controller bias voltage, allowing for single supply operation. The ISL68200 includes a PMBus/SMBus/I2C interface for device configuration and telemetry (VIN, VOUT, IOUT and temperature) and fault reporting. Intersil’s proprietary R4™ control scheme has extremely fast transient performance, accurately regulated frequency control and all internal compensation. An efficiency enhancing PFM mode can be enabled to greatly improve light-load efficiency. The ISL68200’s series bus allows for easy R4™ loop optimization, resulting in fast transient performance over a wide range of applications, including all ceramic output filters. Built-in MOSFET drivers minimize external components, significantly reducing design complexity and board space, while also lowering BOM cost. The 4A drive strength allows for faster switching time, improving regulator efficiency. An integrated high-side gate-to-source resistor helps avoid Miller coupling shoot-through and improve system reliability. The ISL68200 has four 8-bit configuration pins, which provide very flexible configuration options (frequency, VOUT, R4™ gain, etc.) without the need for built-in NVM memory. This results in a design flow that closely matches traditional analog controllers, while still offering the design flexibility and feature set of a digital PMBus/SMBus/I2C interface. The ISL68200 also features remote voltage sensing and completely eliminates any potential difference between remote and local grounds. This improves regulation and protection accuracy. A precision enable input is available to coordinate the start-up of the ISL68200 with other voltage rails, especially useful for power sequencing.
