Renesas Electronics Corporation Integrated Circuits (ICs) - PMIC - Voltage Regulators - DC DC Switching Controllers ISL68312IRAZ-TK

The ISL68312IRAZ-TK is a single-phase digital DC/DC controller designed for use with discrete MOSFETs, compliant with PMBus standards. It utilizes Renesas' ChargeMode control modulation scheme, which ensures stability and fast transient response while minimizing output capacitor requirements. The controller supports an output voltage range of 0.45V to 5.5V and an input voltage range of 4.75V to 16V, with a high output voltage accuracy of 0.5% across varying line, load, and temperature conditions. This device allows for paralleling up to eight controllers for droop-less current sharing, making it suitable for applications requiring scalable power solutions. The integrated DDC serial bus facilitates communication between devices, enabling voltage sequencing and fault spreading without the need for external sequencers. The ISL68312IRAZ-TK also features comprehensive fault management capabilities, including cycle-by-cycle protection for overcurrent, overvoltage, undervoltage, and temperature faults, along with a monitor ADC for real-time telemetry of input and output parameters. Applications for this controller include servers, storage equipment, and telecom/datacom systems, making it a versatile choice for various power supply needs.
