TPS54120EVM-103

The TPS54120EVM-103 is an evaluation module for TPS54120 1A power supply with integrated DC to DC converter & low dropout (LDO) to provide an ultra low noise power supply that delivers quiet power rails to noise sensitive applications. This particular evaluation module configuration contains all of the external components required for a low noise 1A solution with internal thermal and current limit shutdowns, and enable circuitry in a 3.5mm x 5.5mm, QFN, thermally enhanced PowerPad package. The power input of the IC (PVIN) is rated for 1.6V to 17V while the control input (VIN) is rated for 4.5V to 17V. The TPS54120 provides both inputs but this EVM is designed and tested using the PVIN connected to VIN with a minimum input voltage of 7V. The switching frequency is externally set at a nominal 480KHz. TPS54120 provides adjustable slow start, tracking and enable inputs. The TPS54120, including other external components that is capable of delivering up to 1A low noise supply to the load.
