LT8711EFE#PBF

The LT8711EFE#PBF is a DC-DC switching controller from the Voltage Regulator family of PMICs. It is designed to efficiently convert a wide input voltage to a low output voltage with a low external component count and high power efficiency. As a result, it is suitable for applications that require high efficiency, high transient current handling, low component count, and smaller board space.

The LT8711EFE#PBF is a synchronous buck DC-DC controller that operates from an input voltage range of 4V to 36V. It integrates a 168mΩ/240mΩ high-side and low-side power MOSFET, allowing up to 15A of continuous output current. It features programmable output voltage (0.7V to 5.5V) accuracy of ± 1.5%, over-voltage protection, inductor current limit protection, thermal shutdown protection, and under-voltage lockout.

The LT8711EFE#PBF uses a Fixed Frequency Constant Current Mode (CCC) control that maintains a regulated output voltage by controlling the inductor current and modulating the MOSFET switching duty cycle. Using this control, it is able to accurately deliver a regulated output voltage with an efficiency of up to 93%. The controller also provides a programmable soft start and enable/disable function.

The LT8711EFE#PBF is ideal for linear regulators, point of load converters, and various other DC-DC applications requiring high performance and high conversion efficiency. It is available in a space-saving 4 x 5mm QFN package and can be used in applications where board space is limited. It can also be used with an optional external PWM signal to enable pulse skipping mode for extra efficiency and low noise.

In summary, the LT8711EFE#PBF is a highly efficient DC-DC controller designed for applications where high power and cost efficiency are essential. With its small package size, integrated power MOSFETs, and programmable features, it is the perfect choice for battery-operated and other space-constrained applications.
