The ISL6426IV is a fixed output synchronous buck switching regulator designed for efficient DC-DC conversion. It provides a stable output voltage of 1.8V and operates from input voltages of 3.3V to 5V. The device features a simple single-loop voltage-mode control, enabling fast transient response and precise output regulation down to 0.8V. With a programmable switching frequency range of 100kHz to 700kHz, the ISL6426IV allows for the use of smaller surface mount inductors and capacitors, making it suitable for compact designs. The integrated overcurrent protection utilizes the rDS(ON) of the upper MOSFET, eliminating the need for a current sense resistor and enhancing efficiency. The ISL6426IV is available in a 16-lead TSSOP package, compliant with RoHS standards, and is suitable for applications in distributed DC-DC power architectures for DSPs, logic, memory, and microprocessor power supplies.
