description  
The TPS5103 is a synchronous buck dc/dc controller, designed for notebook PC system power. The controller  
has three user-selectable operation modes available; hysteretic mode, fixed frequency PWM control, or SKIP  
control.  
In high current applications, where fast transient response is advantageous for reducing bulk capacitance, the  
hysteretic mode is selected by connecting the Rt pin to Vref5. Selecting the PWM/SKIP modes for less  
demanding transient applications is ideal for conserving notebook battery life under light load conditions. The  
device includes high-side and low-side MOSFET drivers capable of driving low Rds (on) N–channel MOSFETs.  
The user-selectable overcurrent protection (OCP) threshold is set by an external TRIP pin resister in order to  
protect the system. The TPS5103 is configured so that a current sense resistor is not required, improving the  
operating efficiency.
