FEATURES  
DESCRIPTION  
2
Wide Input Voltage Range: 5.5 V to 28 V  
Output Voltage Range: 2 V to 5.5 V  
Built-in 100-mA 5-V/3.3-V LDO with Switches  
Built-in 1% 2-V Reference Output  
The TPS51125 is a cost effective, dual-synchronous  
buck controller targeted for notebook system power  
supply solutions. It provides 5-V and 3.3-V LDOs and  
requires few external components. The 270-kHz  
VCLK output can be used to drive an external charge  
pump, generating gate drive voltage for the load  
switches without reducing the main converter’s  
efficiency. The TPS51125 supports high efficiency,  
fast transient response and provides a combined  
power-good signal. Out-of-Audio™ mode light-load  
operation enables low acoustic noise at much higher  
efficiency than conventional forced PWM operation.  
Adaptive on-time D-CAP™ control provides  
convenient and efficient operation. The part operates  
with supply input voltages ranging from 5.5 V to 28 V  
and supports output voltages from 2 V to 5.5 V. The  
TPS51125 is available in a 24-pin QFN package and  
is specified from -40°C to 85°C ambient temperature  
range.
