description  
The TPS5140 is a dc/dc controller that incorporates three synchronous-buck controllers and one  
nonsynchronous 12-V boost converter on one chip to power the voltage rails needed by notebook peripheral  
components. On-chiphigh-sideandlow-sidesynchronousrectifierdriversareintegratedtodrivelessexpensive  
N-channelpowerMOSFETs. ThenonsynchronousboostconverterincludestheNchannelpowerMOSFETand  
supports 120 mA for the PCMCIA power supply. The outputs are controlled independently and two of the  
synchronous-buck controllers operate 180 degrees out of phase, with the third lowering the input current ripple  
and allowing a smaller input capacitance to reduce power supply cost. For higher efficiency under all load  
conditions, the TPS5140 automatically adjusts each channel from the PWM mode to the skip mode  
independently. The skip mode enables a lower operating frequency and shortens the pulse width to the low side  
MOSFETs, thereby increasing the efficiency under light load conditions. To further extend battery life, the  
TPS5140 features dead-time control and very low quiescent current. Resistorless current protection and the  
fixed high-side driver voltage simplify the system design and reduce the external parts count.
