Analog Devices LTM4709 | Demoboard DC3211A

Description

Demonstration circuit 3211A features the LTM4709, a triple 3A, ultralow noise, high PSRR, and ultrafast μModule® linear regulator with a configurable output array. The input voltage (VINn) range is from 0.6V to 5.5V. There are jumpers to set a 3-bit trilevel code that determines the output voltage (VOUTn) at preprogrammed levels that range from 0.5V to 4.2V. The maximum output current per channel is 3A. The DC3211A requires an external BIAS voltage (VBIASn) at least 1.2V higher than VOUTn and between 2.375V and 5.5V.
