Introduction

The LTC1771EMS8#PBF is a dual mode synchronous controller for DC-to-DC switching conversion which has the combined advantages of pulse-width modulation (PWM) and variable-frequency operations. This synchronous controller is designed for high-efficiency, fixed-frequency, step-down and step-up applications. It operates between 4.5V to 36V and has a maximum switching frequency of 2.4 MHz. It offers an output voltage range of 0.8V to 33V with various current limits. The device supports 32V short circuit protection and is protected from overtemperature, overvoltage and undervoltage conditions.

Application Field

The LTC1771EMS8#PBF is ideally suited for a wide range of applications including motor control, power over Ethernet (PoE) and low voltage backlighting systems. It offers a controller solution for offline (non-isolated) high-current, high-efficiency applications. Its wide input range and two different synchronous modes provide flexible and robust operation in high-power, high-efficiency designs. The device features integrated high and low-side power MOSFETs with embedded control and gate drivers, effectively reducing the number of components needed. It can also be used as an economical replacement for complex discrete designs.

Working Principle

The LTC1771EMS8#PBF utilizes a synchronous-rectified buck or boost topology for its asynchronous operation, allowing the output voltage to track the input voltage and provide high efficiency without the need for bulky components. The device is capable of delivering up to 10A of continuous current while using minimal external components. It features dynamic voltage tracking, which allows the output voltage to be regulated during a constant input voltage. In order to reduce component count, the LTC1771EMS8#PBF integrates a high-side and low-side gate-driver ICM, an internal bootstrap capacitance, and a low-side MOSFET current-sense resistor, all on one monolithic die. The device also provides for standby mode operation for lower power and better light-load efficiency.

Conclusion

The LTC1771EMS8#PBF is a dual-mode synchronous controller designed for high efficiency, fixed-frequency, step-down and step-up applications. It features a wide input voltage range and two separate synchronous modes, allowing it to be used in many different types of applications. The device is capable of delivering up to 10A of continuous current and is protected fromshort circuit, overvoltage, undervoltage and overtemperature conditions. It also includes integrated high and low-side power MOSFETs with embedded control and gate drivers, reducing the need for additional components.
