LTC3374AEUHF Demo Board | High Accuracy 8-Ch Parallelable 1A Sync Bucks; 2.25V ≤ VIN ≤ 5.5V, VOUT1 - VOUT8 = 1V to 3.3V @ 1A

Product Details

Demonstration circuit 2440A is an 8-output power supply featuring the LTC3374A with improved efficiency and accuracy compared to the LTC3374. The LTC3374A has eight 1A synchronous buck regulators each with an independent VIN supply that can range from 2.25V to 5.5V (the minimum VCC supply voltage is 2.7V). The input range of the LTC3374A is ideal for single cell Li-Ion/Polymer battery applications. Up to four buck regulators may be paralleled together to create a higher power buck regulator with a single inductor.
