Description

The LM26420 Evaluation board was designed to provide two 2A outputs, VOUT1 and VOUT2 . It is available in either the eTSSOP package option of the LM26420 for easier probing or the LLP version for evaluating the smaller package. The design emphasizes on the compactness of the LM26420 PCB layout and is thermally optimized. The total solution size is less than 35mm by 40mm. The board supports the conversion from an input voltage ranging from 3V to 5.5V down to output voltages of 0.8V for each channel. VOUT1 and VOUT2 are set to 1.2V and 2.5V respectively. The feedback resistor can be changed to support output voltages as low as 0.8V or as high at 4.5V, assuming VIN is high enough to support it. The EN pins are pulled up to VIN by jumpers for easy evaluation but can also be easily controlled by external logic.
