ISL68312IRAZ-T7A

The ISL683xx family of products from Renesas Electronics America are single-out PWM controllers. These devices have integrated MOSFET drivers with PWM outputs that simplify designing power supplies for data center, wired and wireless communications, and factory automation equipment. The ISL68300IRAZ-T7A can drive discrete external MOSFETs directly, while the ISL68301 pairs with Renesas' smart power stages (SPS) or DrMOS power stages to create a complete voltage regulator solution. The ISL68301 is a PMBus compliant, single-phase digital DC/DC controller for use with SPS and DrMOS power stages. Both devices implement the Renesas fully digital ChargeMode™ control modulation scheme, allowing them to achieve both industry-leading performance and ease of use. ChargeMode control provides an inherently stable control loop that can respond to load transients in a single switching cycle, significantly decreasing output capacitor requirements. A dedicated current share bus allows for paralleling up to eight devices in a current share configuration, allowing support for a wide range of load currents. In conjunction with many other Renesas digital controllers, the ISL683xx family is capable of complex sequencing and fault spreading. The Digital-DC™ (DDC) bus is a single-wire serial bus which provides high-performance inter-device communication without the need for external sequencers, reducing overall system costs.The PMBus interface facilitates device configuration, provides supply telemetry and detailed fault reporting including a parametric capture tool (SnapShot). These features are conveniently accessible through the PowerNavigator™ software tool. Additionally, a wide array of common configuration options are independently configurable through use of pin-strap resistors. The rich feature set in conjunction with the PowerNavigator software tool make the ISL683xx products ideal for telecom, servers, storage equipment, and power supply applications.<strong>Features:</strong> Unique compensation-free design, which is always stable, Output voltage range: 0.45 V to 5.5 V, Input voltage range: 4.75 V to 16 V or 4.5 V to 5.5 V, 0.5% output voltage accuracy over line, load, and temperature, ChargeMode control achieves fast transient response, requires minimal output capacitance, and provides output stability without compensation, Single-channel output can be paralleled with up to eight devices in a single droop-less current sharing output, Switching frequency range of 200 kHz to 1.0 MHz, Proprietary single-wire DDC serial bus enables voltage sequencing and fault spreading with other Renesas digital power ICs, Cycle-by-cycle inductor peak current protection, Configurable fault protection for output voltage UV/OV, input voltage UV/OV, internal and SPS temperature, Cycle-by-cycle output current measurement with adjustable gain settings for sensing with SPS current monitor or low DCR inductors, Dedicated telemetry ADC monitors input voltage, input current, output voltage, internal temperature, and power stage temperature, Nonvolatile memory (NVRAM) stores operating parameters and fault events across POR cycles, PMBus compliant; supports 113 PMBus commands, Compatible with SPS devices, Servers and storage equipment, Telecom and datacom equipment, Power supplies (FPGA, ASIC, DSP, memory)
