Intersil's ISL8009 is a high-efficiency, 1,5 A synchronous buck integrated FET regulator suitable for point-of-load regulation for datacom/telecom, battery powered systems, medical instrumentation and several industrial applications. The ISL8009 is designed to utilise a special multi-operation capability, allowing selection between forced PWM mode and automatic PWM/PFM mode. This ability to switch between modes enables the regulator to maintain up to 95% efficiency in both full load and light load conditions. Additionally, when the device is in PFM mode, the quiescent current drops to 17 μA and makes the ISL8009 ideal for battery powered applications. The ISL8009 includes features like high 1,6 MHz switching frequency, allowing the use of smaller external components. The device also has internal current mode compensation to eliminate the need for external components while contributing to fast transient response in over-current conditions. Other important features include Power-On-Reset (POR) and Enable (EN) to provide output voltage monitoring and power sequencing capabilities, further eliminating the need for additional discrete ICs.
