DATASHEET ISL68300 FN8789 Rev.0.00 Scalable Single Output Digital PWM Controller with Integrated Driver and Jun 7, 2018 PMBus The ISL68300 is a PMBus compliant, single-phase Features digital DC/DC controller optimized for use with discrete Unique compensation-free design, which is always MOSFETs. stable The ISL68300 implements the Renesas fully digital Output voltage range: 0.45V to 5.5V ChargeMode control modulation scheme, allowing it Input voltage range: 4.75V to 16V or 4.5V to 5.5V to achieve both industry leading performance and ease of use. ChargeMode control provides an inherently stable 0.5% output voltage accuracy over line, load, and control loop that can respond to load transients in a single temperature switching cycle, significantly decreasing output capacitor ChargeMode control achieves fast transient response, requirements. reduced output capacitance, and provides output A dedicated current share bus allows for paralleling up to stability without compensation eight devices in a current share configuration, allowing Single-channel output, can be paralleled with up to support for a wide range of load currents. eight devices in a single droop-less current sharing In conjunction with many other Renesas digital output controllers, the ISL68300 is capable of complex Switching frequency range of 200kHz to 1.0MHz sequencing and fault spreading. The Digital-DC (DDC) bus is a single-wire serial bus which provides Proprietary single-wire DDC serial bus enables high performance inter-device communication without voltage sequencing and fault spreading with other the need for external sequencers, reducing overall system Renesas digital power ICs costs. Cycle-by-cycle inductor peak current protection The PMBus interface facilitates device configuration, Digital fault protection for output voltage UV/OV, provides supply telemetry and detailed fault reporting input voltage UV/OV, and temperature including a parametric capture tool (SnapShot). All of Cycle-by-cycle output current measurement with these features are conveniently accessible through the adjustable gain settings for sensing with high current, PowerNavigator software tool. Additionally, a wide low DCR inductors array of common configuration options are independently configurable through use of pin-strap Monitor ADC measures input voltage, input current, resistors. output voltage, internal temperature, and external temperature The ISL68300 supports a comprehensive fault management system, with dedicated hardware support Nonvolatile memory (NVRAM) for storing operating for cycle-by-cycle overcurrent, overvoltage, parameters and fault events undervoltage, and temperature faults. The configurable PMBus compliant, supports 112 PMBus commands fault response system is capable of latching off or restarting the output on a fault-by-fault basis. Integrated Applications LDOs for device and gate driver bias allow for single Servers and storage equipment supply operation. Telecom and datacom equipment A companion device, the ISL68301, has a PWM output, Power supplies (FPGA, ASIC, DSP, memory) which can be paired with the Renesas family of Smart Power power stages or DrMOS devices.
