UDT020A0X3-SRZ

The 20A Digital MicroDLynxTM power modules are non-isolated dc-dc converters that can deliver up to 20A of output current. These modules operate over a wide range of input voltage (VIN = 3Vdc-14.4Vdc) and provide a precisely regulated output voltage from 0.6Vdc to 5.5Vdc, programmable via an external resistor and PMBusTM control. Features include a digital interface using the PMBusTM protocol, remote On/Off, adjustable output voltage, over current and over temperature protection. The PMBusTM # interface supports a range of commands to both control and monitor the module. The module also includes the Tunable LoopTM feature that allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.
