ISL6540AIRZ

The ISL6540AIRZ is a dc-dc switching controller IC marketed by Intersil Corporation.

The product has a 5V to 28V input, 200kHz switching frequency, and 0.5A peak and 0.33A RMS internal switch current. It is designed for step-down and step-up applications with a wide range of output voltages and current levels.

The product is suitable for use in applications such as battery management, powerline conditioning, portable equipment and industrial power supply. It can also be used for dc-dc converters for automotive, consumer and computer applications.

The product is based on a pulse-width modulation (PWM) architecture which provides high efficiency and fast transient response by using a low on-resistance internal switch, integrated current limit and synchronous rectification to reduce losses. It also offers over-current and over-temperature protection.

The ISL6540AIRZ is a highly integrated design with integrated voltage and current feedback circuitry. It includes frequency synchronization, adjustable output voltage and current limit, internal soft start and selectable power save mode.

The product supports a wide range of output voltages and is capable of sourcing or sinking currents up to 0.5A, relying on an input voltage between 5V and 28V. The package features a non-tracking current-sense voltage and a logic compatible enable input, allowing for circuit simplification.

Overall, the ISL6540AIRZ is an ideal dc-dc switching controller for a variety of applications. It provides high efficiency, low on-resistance switch and fast transient response. With switch current by 0.5A peak and 0.33A RMS and adjustable output voltage, it\'s also suitable for battery management, powerline conditioning, portable equipment and industrial power supply.
