TPS5103 Datasheet (Texas Instruments) - Multiple Mode Synchronous DC/DC Controller

TPS5103, Multiple Mode Synchronous DC/DC Controller

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 f
