The ISL8105BCBZ-T is an integrated circuit (IC) component manufactured by Renesas Electronics. It is a dual synchronous buck controller designed for applications that require high efficiency and compact size. This IC is widely used in computing, consumer electronics, and industrial applications.
One of the key features of the ISL8105BCBZ-T is its ability to deliver up to 2.5A continuous output current per channel, allowing it to efficiently power a wide range of loads. The IC operates from a single power supply with a voltage range of 4.5V to 18V, making it compatible with different power sources.
The device incorporates a synchronous-rectified buck converter topology, which eliminates the need for an external Schottky diode, thereby reducing component count and cost. It also employs a voltage mode control scheme, which provides fast transient response and excellent load regulation. Additionally, it features a fixed PWM frequency of 500kHz, ensuring efficient operation and minimizing external component size.
The ISL8105BCBZ-T integrates various protection features to safeguard the system. It includes overvoltage protection (OVP), undervoltage protection (UVP), and overcurrent protection (OCP), which prevent damage to the IC and the load under fault conditions. Thermal shutdown protection (TSD) is also included to prevent overheating
