Automotive boost converter with wide-range programmable output
The TPS613785QWRTERQ1 is a Texas Instruments automotive-grade step-up (boost) converter, AEC-Q100 qualified, in a 16-WQFN exposed-pad package. It accepts an input from 2.3 V to 14 V and delivers a programmable output from 4 V up to 18.5 V — covering the 12 V battery rail and post-boost rails for infotainment, ADAS sensors, and ECU sub-supplies.
Switching frequency and synchronous rectification
The switching frequency is programmable across 200 kHz to 2.2 MHz, letting the designer trade inductor size against efficiency.
