SBVS180C JANUARY 2012REVISED JUNE 2012  
Low-Noise, 1-A Power Supply  
with Integrated DC-DC Converter and Low-Dropout Regulator

FEATURES  
DESCRIPTION  
The TPS54120 combines the high-efficiency of a  
Low-Noise Output: 17 µVRMS at 100 Hz to  
1 MHz  
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 noise-  
sensitive applications.  
Wide Input Voltage Range: 4.5 V to 17 V  
High Efficiency: 72% at 1 A, 12V Input  
Excellent Load/Line Transient Response  
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.  
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  
The device is available in a space-saving, 3.5-mm ×  
5.5-mm QFN package, and is specified to operate  
over a –40°C to +125°C junction temperature range.
