AEC-Q100

The Texas Instruments synchronous buck regulator is designed to work well in multi rail power supply architectures. The output voltage of the device can be configured to track a higher voltage rail using the SS TRK pin. If the output of the regulator is pre biased at start up it will not sink current to pull the output low until the internal soft start ramp exceeds the voltage at the feedback pin.

Available in AEC Q100 temperature grade 1

Accurate current limit minimizes inductor size

Adjustable soft start with external capacitor

Precision enable pin with hysteresis
