The ISL6843IB-T is a high-performance, high-efficiency, H-Bridge-angle modulation, synchronous DC-DC controller with integrated FETs. It integrates the entire high-side and low-side power MOSFETs on one small chip, while allowing advanced control functions. Able to generate high-efficiency solutions suitable for a wide range of applications, it offers users design flexibility and protection features to help reduce complexity, board space, and overall system cost.

Application Field:

The ISL6843IB-T is typically used in products where a DC/DC converter is required, such as portable and embedded power systems, smart phones, tablets, and other mobile devices. Its advantages include small size and low output ripple current, which offers greater design flexibility and low-noise solutions compared to other solutions. Moreover, the device offers excellent thermal performance and can support up to 6A of continuous output current.

Working Principle:

The ISL6843IB-T works on a hysteretic inductor Current Mode (HCM) architecture with a digital-controllable variable switching frequency, allowing the maximum switching efficiency to be achieved at all loads. The controller is also capable of providing variable voltage and current limit. The device can detect the output voltage and skip the switching cycle if the voltage is above the upper voltage limit or below the lower voltage limit. An external RC filter is used to smooth the output ripple. The device also features a comprehensive set of protection features, including over-current protection and over-temperature protection.

In summary, the ISL6843IB-T is an integrated high-efficiency, H-bridge-angle modulation, synchronous DC-DC controller that is applicable to a wide range of applications, such as portable and embedded power systems, smart phones, tablets, and other mobile devices. With its integrated FETs and variable switching frequency, the device provides the user with design flexibility and protection features to reduce design complexity, board space and overall system cost.
