The LTC3868IGN-1#TRPBF is a high efficiency, synchronous step-down DC/DC controller that is typically used in power systems where high efficiency and small size is required. The device has a wide 6V to 60V input voltage range and a wide output voltage range of 0.6V to 5V. It offers high current capability, up to 12A, and is ideal for applications that require multiple power rails.

The controller is perfectly suitable for portable electronics, such as laptop and netbook computers. It provides high efficiency even at lower output currents, where efficiency is usually not so great with conventional controllers. Its combination of wide input voltage range, high output current capability and extremely low noise make it ideal for a variety of automotive, industrial, wireless, and consumer applications.

The LTC3868IGN-1#TRPBF has an integrated voltage-mode based architecture that utilizes the latest high-speed CMOS process technology. This enables the device to achieve switching frequencies up to 1.35MHz. The device also provides low output voltage ripple, a fast transient response and a wide output voltage range. The LTC3868IGN-1#TRPBF also includes a power-good indicator, soft start, output voltage tracking and auto-restart function to facilitate over-voltage and over-temperature protection. The device is also equipped with an overtemperature protection circuit to avoid any damage due to excessive temperature.

The LTC3868IGN-1#TRPBF features programmable frequency, current-sense threshold, soft-start rate and tracking delay. It also includes a low-side driver enable pin that can be used to enable/shutdown the device in standby mode. The device can operate in either Continuous Conduction Mode or Discontinuous Conduction Mode. The CCM is recommended for high ambient temperature applications as it reduces switching losses, while the DCM offers higher conversion efficiency at light load or no load conditions.

In addition, the LTC3868IGN-1#TRPBF supports a voltage-mode current-mode charge pump for constant frequency operation. The device supports over-voltage and over-current protection and is available in the compact 24-pin 4x4 QFN package.

The LTC3868IGN-1#TRPBF is well suited for a wide range of DC/DC mobile applications and backup power supplies that require high efficiency and low noise operation. Examples of these applications include tablet PCs, portable medical instruments, automotive infotainment systems, wireless base stations, consumer electronics, and portable consumer electronics.

Overall, the LTC3868IGN-1#TRPBF is a high-efficiency synchronous step-down DC/DC controller, ideal for applications requiring multiple power rails and where efficiency and small size are required. It features a wide input and output voltage range, high output current capability and low noise operation. The device also includes a range of protection and control features and is available in the compact 24-pin 4x4 QFN package.
