descriptionThe 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 resistor in order to
protect the system. The TPS5103 is configured so that a current-sense resistor is not required, improving the
operating efficiency.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
