LTC7815EUHF#TRPBF

PMIC - Voltage Regulators - DC DC Switching Controllers

The LTC7815EUHF#TRPBF is a monolithic synchronous buck controller ideal for high current point of load power supplies. It achieves extremely high efficiency, up to 96.8%. It offers up to 7A output current and up to 3A load step response, making it well suited for a wide range of application needs.

Application Field

The LTC7815EUHF#TRPBF is designed for high power applications that require high output current and low output voltage ripple. It is ideal for use in data centers and cloud computing applications, as well as for distributed power architectures. It can also be used in telecom, automotive, and aerospace applications.

Working Principle

The LTC7815EUHF#TRPBF is based on a synchronous buck topology, which is highly efficient and offers superior performance compared to traditional diode-based solutions. It employs a switching buck circuit that switches power between the input and output to regulate the output voltage.

The controller includes an internally-generated clock and a PWM comparator that maintains a fixed frequency. The frequency is adjustable by an external resistor. It can also be programmed to ramp up or down quickly for fast load current response or to provide a smooth transition during input or output transients.

The LTC7815EUHF#TRPBF features programmable soft-start, overvoltage protection, and overcurrent protection. It also includes a switching frequency synchronization feature which allows for the connection of multiple voltage regulators so the output voltages are in-phase, increasing the useful life of the power supply components.

Conclusion

The LTC7815EUHF#TRPBF is a highly efficient monolithic synchronous buck controller that offers excellent performance in high current point of load applications. It is well suited for use in data centers, cloud computing, and distributed power architectures, as well as in automotive, aerospace, and telecom applications. Its programmable features make it easy to use and configure for a variety of applications.
