1.1 Background

The EVM is setup to allow the user to see the performance of the TPS54J060 and TPS54J061 devices and easily make changes to multiple settings. The low drain-to-source on resistance of the MOSFETs allows the device to achieve high efficiencies and helps keep the junction temperature low at high output currents. There is no need for external compensation components since this device is designed with D-CAP3™ control topology. On the EVM the switching frequency and the operation mode are externally selectable using a jumper to set the resistor from the MODE pin to AGND. An external resistor divider allows for an adjustable output voltage. Additionally, the device provides adjustable soft start, adjustable OC limit threshold, external reference input, and an open-drain power good indicator. Lastly the device has a fixed internal VIN under voltage lockout and externally adjustable UVLO using a resistor divider at the EN pin.
