| Manufacturer | Texas Instruments (https://www.ti.com/) |
| 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 con... |
| Features |
citance, 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.
