Texas Instruments is promoting a new dual output power supply for automotive applications it says can improve the start-stop function in new car models by ensuring stable, uninterrupted output voltages, “even in cases where the input voltage drops significantly below the output voltage levels.”
The TPS43330-Q1 family, TI says, “remains fully functional during such voltage drops and ensures that applications continue to work without interruption or performance reduction.
“The devices’ ultra-low quiescent current makes the use of a separate standby voltage supply unnecessary, thus reducing system cost and complexity,” TI adds.
The new power supply can extend battery life, and allow for simpler, lower-cost filters as it reduces conducted electromagnetic interference
