The ISL6527ACBZA is a DC/DC switching controller designed to provide superior transient performance and low system noise. It provides the superior accuracy, fast transient response, and low system noise enabled by the intelligent current limit, robust integrated gate drive, and selectable non-overlap clock synchrones with up to 95% efficiency. The ISL6527ACBZA is available in a small, thermally enhanced 8-mL footprints package ideal for high performance, space-sensitive applications.

The ISL6527ACBZA has a wide range of applications, including mobile computing, automotive, datacom, telecom, and industrial control systems. This DC/DC switching controller is designed to work with external MOSFETs to provide a low power, high efficiency power supply with excellent transient response and superior noise characteristics. It is excellent for systems needing very low external parts count or in cases where efficiency and board space are primary concerns.

The ISL6527ACBZA also offers superior accuracy and fast transient response with its intelligent current limit circuit. The intelligent current limit circuit combines fast response and accurate loop control leading to very fast load transients and fast and accurate droop current limiting. The integrated circuit also features an integrated gate drive that allows for faster switching speed, higher efficiency, and low on-resistance due to its fast ramp rate, good output drive, and accuracy of the power MOSFET drive.

The integrated selectable non-overlap clock synchrones enables the ISL6527ACBZA to drive two PMOS transistors as a powerful synchronous driver, providing up to 95 percent efficiency in DC/DC converters. The non-overlap clock synchrones also reduces system noise, resulting in lower EMI emissions.

In addition, the ISL6527ACBZA provides integrated programmable input . Undervoltage, overvoltage and overcurrent protection features are also provided, providing the safety and reliability required for power sensitive systems. The integrated programmable input voltage, programmable soft start and programmable switching frequency ensure the ISL6527ACBZA is an ideal product for all types of DC/DC converter applications.

The ISL6527ACBZA provides superior transient response and low system noise making it ideal for high-end applications that require superior transient performance,excellent accuracy and fast transient response, and low EMI/RFI emissions. It is also a space-saving choice due to its 8-mL footprint and its ability to drive two PMOS transistors with a single non-overlap clock. With its intelligent current limit and programmable timing, the ISL6527ACBZA is the perfect choice for DC/DC converter applications that require superior performance and reliability.
