The LTC7815HUHF#TRPBF is part of the LTC voltage regulator family. It is designed to provide a complete DC-DC switching converter solution for a wide range of applications including telecom and datacom switching supplies, DC/DC non-isolated servers, and high-efficiency LED lighting. It is the first ever fully integrated synchronous current mode controller with a 45V SenseFET helping to reduce the system footprint by over 50%. This makes it ideal for high power applications that are space-constrained.

The LTC7815HUHF#TRPBF is a dual path synchronous current mode system controller which operates in peak current mode control and contains a proprietary FET SenseFET™ device designed to ensure accuracy, robustness and low power consumption. This makes it suitable for a wide range of switching power supply applications. The device also contains a number of safety features, including integrated overvoltage protection and thermally foldback protection. Furthermore, the device is designed to reduce EMI and meet the requirements of Class B shut down.

The working principle of the LTC7815HUHF#TRPBF is simple. The device is a self-energized, single-channel topology. It modulates the on/off time of a MOSFET switch at 0.5MHz switching frequency to match an external sense resistor. The voltage applied to the MOSFET switch is sensed and regulated by the internal FET SenseFET™ device. This ensures that the voltage applied to the MOSFET switch is always within a few mV of the intended value. In addition, the maximum duty cycle limit of the device is adjustable, allowing for accurate current mode control.

The LTC7815HUHF#TRPBF is an ideal device for a wide range of applications. It provides an economical, high-efficient and low-EMI solution for telecom power supplies, servers and LED lighting driver applications. Its fully integrated synchronous current mode controller, along with the FET SenseFET™ device, allows for improved design flexibility and easy adaptation to a wide range of switching requirements. Plus, its integrated protection features, wide input voltage range and adjustable maximum duty cycle make it an ideal solution for a number of different applications.
