Output 12.5 V / 2 A
Output 21.2 V / 2 A
IC revisionB

Description

The LM26400Y demonstration board was designed to provide two 2A outputs at 1.2V and 2.5V respectively. It uses the ETSSOP package option of the LM26400Y for easier probing. The design emphasizes on the compactness of the LM26400Y PCB layout and is thermally optimized. The total solution size is about 20mm by 30mm. The board supports the conversion from an input voltage ranging from 5V to 20V down to output voltages of 1.2V and 2.5V. With the availability of a separate 5V rail and a couple of small bootstrap diodes, the board also supports an input voltage down to 3.3V with 2A output currents. The EN pins are pulled up to VIN by default for easy evaluation but can also be easily controlled by external logic.
