SBVS375B July 2019 – April 2020 TPS7A03
The TPS7A03 includes several innovative circuits to ensure excellent transient response. Dynamic biasing increases the IQ for a short duration during transients to extend the closed-loop bandwidth and improve the output response time to transients.
Adaptive biasing increases the IQ as the DC load current increases, extending the bandwidth of the loop. The response time across the output voltage range is constant because a buffered reference topology is used, which keeps the control loop in unity gain at any output voltage.
These features give the device a wide loop bandwidth during transients that ensures excellent transient response while maintaining low IQ in steady-state conditions.
