It can also be used to provide DC to DC conversion for applications such as solar, automotive, embedded systems, and communications.

The working principle of the LM5088MH-2EVAL/NOPB evaluation board is based on the Dual Inductor Buck Boost Converter (DIBBC) topology. This device utilizes two series connected inductors to effectively increase or decrease the input voltage depending on the required output voltage. When the output voltage is higher than the input, the device increases the input voltage to reach the output voltage. When the output voltage is lower than the input, the device reduces the input voltage. The device then uses the two MOSFETs to switch the current between the two inductors for the appropriate voltage conversion.

The LM5088MH-2EVAL/NOPB evaluation board has a number of internal features including: an input voltage disconnect configuration; output current limit; soft-start and under-voltage lockout; frequency foldback. These internal features combined with the external components, ensure the board provides a complete power solution for low voltage/high efficiency DC to DC conversion.

Overall the LM5088MH-2EVAL/NOPB evaluation board provides a complete power solution for low voltage/high efficiency DC to DC conversion. Its wide input voltage range (3.3V to 16V) and integrated MOSFETs make it ideal for a wide range of applications including portable electronic devices, LED drivers, laser diodes, servo motors, amplifiers, and solar, automotive, embedded systems, and communications.
