ISL68201数据手册开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF

描述 Description

The ISL68201 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 ISL68201 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 ISL68201’s serial bus allows for easy R4 loop optimization, resulting in fast transient performance over a wide range of applications, including all ceramic output filters. The ISL68201 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 ISL68201 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 ISL68201 with other voltage rails, especially useful for power sequencing.
