CHL8104-09CRT

CHL8104-09CRT Application Field and Working Principle

The CHL8104-09CRT (Open-Drive R2R Step Down Controller) is a type of DC DC switching controller and part of PMIC (power management integrated circuits) which is used to regulate the output of voltage from the power source. It is a highly integrated, low power and low-noise DC converter suitable for high temperature application such as automotive and industrial systems.

The CHL8104-09CRT features two R2R (resistor to resistor) step down DC-DC converters. It includes two independent output channels with a high Efficiency (up to 90%) of the step down voltage conversion. This means that there is less power consumption and less heat generation in appliances, resulting in longer life and enhanced performance.

The CHL8104-09CRT also features a robust, advanced voltage feedback and current sense architecture which allows for high accuracy and stable operation at very low ripple. The low noise feature makes it ideal for applications requiring low noise. It is also designed to be protective against overcurrent, overvoltage and thermal shutdown.

The CHL8104-09CRT allows for variable output voltage and current limits, adjustable current limit and soft-start functionality which make it suitable for multi-load power management applications. The current sense architecture allows for self-regulation of the output voltage and current. This makes it easy to adjust the current limit to ensure system stability in the event of an overload or short circuit.

In summary, the CHL8104-09CRT is a highly integrated and efficient DC-DC switching controller which is suitable for a wide range of applications including automotive and industrial systems. It has a robust and advanced voltage feedback and current sense architecture, allowing for high accuracy and low noise operation. The adjustable current limit and soft-start make it ideal for multi-load power management applications.
