This EVM utilizes TI’s TPS51220A in a dual output design. It includes many test points to help the engineer monitor and evaluate the control characteristics of the TPS51220A. The TPS51220A is a dual peak current mode synchronous buck controller with three linear regulators. The EVM also allows the engineer to configure several of the features of the TPS51220A controller.The TPS51220A EVM-476 provides two 8-A outputs, 3.3 V and 5 V. It accepts an input voltage from 8 V to 20 V. Several jumpers and switches allow the user to evaluate various control functions of the TPS51220A. Switches provide an easy method to enable and disable the EVM or each of the two outputs independently. Two jumper blocks allow the user to select the mode of operation of each output. One jumper block allows the engineer to select the control architecture and OVP function. And one block allows for selection of over current trip level and if the output is discharged by the converter. See sectionsbelow for more details.
