Single-Phase R4 Digital Hybrid PWM Controller with PMBus/SMBus/I2C and PFM
FN8696 Rev.5.01 Feb 16, 2023
The ISL68201 is a single-phase, synchronous buck PWM controller featuring the Renesas 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 ISL68201 includes a PMBus/SMBus/I2C interface for device configuration and telemetry (VIN, VOUT, IOUT, and temperature) and fault reporting.
The Renesas proprietary R4 control scheme has extremely fast transient performance, accurately regulated frequency control, and all...
