TPS54120 www.ti.com SBVS180C – JANUARY 2012 – REVISED JUNE 2012 Low-Noise, 1-A Power Supply with Integrated DC-DC Converter and Low-Dropout Regulator FEATURES 1 • Low-Noise Output: 17 µVRMS at 100 Hz to 1 MHz • Wide Input Voltage Range: 4.5 V to 17 V • High Efficiency: 72% at 1 A, 12V Input • Excellent Load/Line Transient Response • Synchronizable to External Clock: 200 kHz to 1.2 MHz • Small Package: 3.5 mm × 5.5 mm QFN-24 APPLICATIONS • Telecom Infrastructure • Pico and Femto Base Stations • Powering Sensitive Clocking Distribution Circuits • Test and Measurement • Powering RF Components: VCOs, Receivers, ADCs • Professional Audio DESCRIPTION The TPS54120 combines the high-efficiency of a step-down switching (dc-dc) converter with a high power-supply rejection (PSR), low-noise, low-dropout regulator (LDO) to provide an ultra low-noise power supply that delivers quiet power rails to noisesensitive applications. With a wide input range of 4.5 V to 17 V, the TPS54120 is ideally suited for systems with 12-V power busses, and supports a 1-A continuous output current. The output voltage can be set from 0.8 V to 6.0 V using external resistors. The dc-dc converter and LDO are completely configurable, allowing the TPS54120 to be used in a wide range of low-noise applications. In addition, the TPS54120 includes features such as softstart, switching frequency synchronization, and a power-good signal. The device is available in a space-saving, 3.5-mm × 5.5-mm QFN package, and is sp.
