Texas Instruments TPS548B27EVM-162 Converter Evaluation Module

Texas Instruments TPS548B27EVM-162 Converter Evaluation Module (EVM) is designed to demonstrate the TPS548B27. The TPS548B27 is a D-CAP3 synchronous buck converter designed for up to 20A output current. The evaluation module was designed to illustrate the small printed circuit board that may be achieved when designing with this device. The evaluation module allows the user to make changes to multiple settings quickly. The low drain-to-source on-resistance of the MOSFETs enables the device to achieve high efficiencies and 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. The evaluation module’s switching frequency and 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 flexible soft start, adjustable OC limit threshold, external reference input, and an open-drain power good indicator. The Texas Instruments TPS548B27 device has a fixed internal VIN under-voltage lockout and externally adjustable UVLO using a resistor divider at the EN pin.
