LT8607EMSE#PBF

Introduction

The LT8607EMSE#PBF is a high-efficiency, high-side, synchronous, buck current-mode switching regulator controller for industrial and consumer applications. It offers a regulated output voltage at up to 4A from a +4.5V to +48V input voltage range with ±1% (typical) output voltage regulation accuracy. The LT8607 uses a current-mode design for fast transient response and is driven by an external MOSFET. The switching frequency is adjustable from 50kHz to 500kHz with a single resistor to allow design flexibility.

Application Fields

The LT8607EMSE#PBF is suitable for a wide range of high-current, high-efficiency DC-DC conversion applications such as telecom, server and networking equipment, DC/DC bus power converters, and point-of-load or intermediate bus converters in industrial control and automotive applications. It can be used in systems where it\'s necessary to regulate current, voltage and temperature. The LT8607EMSE#PBF also provides input filtering for clean waveforms.

Working Principle

The LT8607EMSE#PBF operates using switch-mode current-mode power conversion. Its internal waveform offset generator circuit in conjunction with a high-side MOSFET provides for fast transient response and minimum output voltage ripple. The external MOSFET enables higher efficiency and higher current solution. In order to achieve steady-state performance, the output voltage is sensed and regulated using current-mode feedback control. The switching frequency is adjustable from 50kHz to 500kHz using an external resistor, which allows the circuit to operate at a wide range of frequencies. The LT8607EMSE#PBF also offers a current, voltage and temperature protection feature to protect against over-current, over-voltage and over-temperature conditions.

Conclusion

The LT8607EMSE#PBF voltage regulator is a high-performance and reliable switching regulator, ideal for high-current, high-efficiency DC-DC conversion applications. It offers a regulated output voltage and provides fast transient response and high-efficiency through a current-mode design. The switching frequency is adjustable from 50kHz to 500kHz with a single resistor, which allows for design flexibility. The LT8607EMSE#PBF also provides input filtering for clean waveforms and offers current, voltage and temperature protection.
