Application Field of the LTC3126EFE#PBF

The LTC3126EFE#PBF is designed for automotive, industrial, and energy harvesting applications. It is especially useful in high current applications with extreme space constraints, since it can provide up to 2A of output current and operates from a 4.5V to 80V input, while still maintaining high efficiency. It can also be used in point-of-load applications and energy harvesting systems, due to its wide VIN range, low quiescent current, and high efficiency. Additionally, it can be used to power microcontrollers, sensors, FPGAs, and other devices that require a high-current supply with extreme space constraints.

Working Principle of the LTC3126EFE#PBF

The LTC3126EFE#PBF is a synchronous step-up/step-down switching regulator that utilizes a fixed frequency, current mode, PWM control architecture. The device utilizes an input voltage ranging from 4.5V to 80V, and has an adjustable output voltage range between 0.6V and 5V. It can operate in both step-up and step-down mode and provides up to 2A of continuous output current. The device also features programmable loop compensation and soft-start to optimize performance and minimize load transients.

The switching regulator operates by turning an internal switch on and off at a rate determined by the frequency and duty cycle of the PWM control. In step-up mode, the device charges an output capacitor when the switch is on, and discharges it when the switch is off. The output voltage is determined by the capacitance and voltage of the output capacitor and the duty cycle. In step-down mode, the energy stored in the inductor is used to charge the output capacitor, and the output voltage is regulated by the PWM control.

Overall, the LTC3126EFE#PBF is a versatile synchronous step-up/step-down DC/DC switching regulator optimized for maximum efficiency, power density, and low cost in point-of-load applications. It is ideally suited for automotive, industrial and energy harvesting applications, and offers a wide VIN range and high efficiency.
