DC-DC converters are used to transfer direct current (DC) from one voltage level to another. The LTM8020EV#PBF is a dual-input, high-efficiency, non-isolated DC-DC converter and is capable of synchronous rectification for powering FPGA applications. The module offers accurate voltage regulation and high efficiency in a small, surface-mount package.

The LTM8020EV#PBF features an integrated 35-A power stage with high-side and low-side MOSFETs, coupled with an adaptive onboard driver. The module offers an output voltage range of 3.3-20V and adjustable AC and DC input voltage ranges of 6-36 and 7.5-50 V, respectively. The device can effectively manage multiphase applications, enabling a wide range of current in low-side or high-side applications. It also features a digital programmable input/output voltage setpoint, enabling 1 percent regulation accuracy.

In terms of efficiency, the module offers up to 95.5 percent efficiency under optimal working conditions. It also features low-impedance output voltage sensing and optional HOTswitch low quiescent current. In addition, the converter comes with a wide temperature range of -4°F to +125°F, which allows it to be used in extreme temperature environments. The module is available in a compact 24-pin Thin Small-Outline Package (TSOP) package.

The LTM8020EV#PBF’s application field includes FPGA and ASIC power management, processor and active component power management, as well as power supply design. Its modular design and small package size helps reduce system form factor and component footprint. Its adaptive driver reduces external components required for powering the device.

The main working principle of the LTM8020EV#PBF is synchronous rectification. It works by alternately switching the upper and lower MOSFETs on and off, allowing current to flow in both directions. The output voltage is regulated by using the feedback voltage and then controlling the duty cycle of the switching elements. As the current demand changes, the process is repeated to maintain a constant output voltage.

In conclusion, the LTM8020EV#PBF is an efficient, dual-input, non-isolated DC-DC converter for powering FPGA applications. It offers an output voltage range of 3.3-20V, an adjustable AC and DC input voltage range of 6-36 and 7.5-50 V, respectively, and a wide temperature range. In addition, the small form factor and low quiescent current enable its application in numerous fields, while the synchronous rectification principle allows it to efficiently regulate the output voltage.
